I can tell you what *I* know *I've* always been like, but I'm no expert. (By the way, you might find more help in the 'parents' section.)
I have always:
1. 'Picked' constantly. Pills off clothing, scabs off knees, you name it. Principally fingernails and cuticles.
2. Had a hard time remembering the original subject of a conversation, and a harder time sticking to it.
3. Gone into little 'ADD comas'. If nobody is talking to me or asking anything of me, I will freeze, like a wax figure, stare somewhere beyond what I seem to be looking at, and completely and entirely tune out from whatever is happening.
4. Talked WAY too much.
5. Commited the same little sins as any kid (not making my bed, not brushing my teeth, etc), except I continue to commit them no matter how many times I am reminded, scolded, or punished. To this day I almost never remember to look both ways before crossing the street, and therefore my number of autobile-related near-death experiences are countless.
Hope that helped! :)
Fed up - I cope by firstly accepting my situation and understand the card I have been dealt (this gives a lot of peace)
adhd children are high maintenance and it is nearly impossible to enjoy anything!. I have learnt that I have to give up on my own social life to give more time to my children. I have sacrificed a lot. The reward for this is to see them flourishing and succeeding.
I sometimes become resentful of the loss of my own life, but then I tell myself, they will leave home one day. lol.
I think it is making it your life to raise this kid and doing your best for them as your priority. I find if I spend enough time just sitting with my kids while they watch TV or go outside and watch them as they yell "watch me mum", helps our relationships to grow. I get very sick and tired of all the yelling and forcing and draggng them around that I do because of their behaviour, so these little good times are what glues us together.
Not sure if this helps!
i have an 11 year old boy that has sever ADHD I have beenHeh, I'm gonna be a writer, but for some reason I don't see anything I write as that funny, so it kinda discombobulates me when people report falling off of their chair. 
But thanks. 
Rayndrop,
You have such insight! It's very helpful for me to read your posts about yourself so that I can understand my sweet son a little bit better. I'm wondering, do you have any siblings? Do they have any tricks on dealing with the whole ADHD thing? I have a 13yo daughter that is wonderful and very mature, and from the big picture view, she is an awesome sister... but, she sometimes has a hard time dealing with her little brother and the amount of attention he often needs to get through homework or when we work on how to build relationships, etc. As an adult, I can understand her bouts of jealousy, and even though we work hard to give her special time, and explain what is going on, sometimes she hits the wall, too. Ya know what I mean? I definately give her 1-1 time, but sometimes, it's just not enough, after all, she IS a 13yo girl.
Amberdawn - to add to Ryndrops list:
1. talking, talking, talking, talking to anybody, anytime, anywhere.
2. trouble staying on task and/or following a sequence of instructions to completion. (we make lists and stick them on his door to help him remember his morning routine)
3. difficutly reading social cues from the other kids, thus, difficulty making and maintaining friendships.
4. doesn't understand the concept of 'space'.
5. immature compared to others in the same peer group.
6. Did anybody mention talking a lot? 
All of these things have gotten better for my son as he matures (except for the excessive talking) and we keep working through them. Also, review the list of recommended reading on this site for some great books on what to expect and strategies to deal.
Much luck.
Dear Krobb, I used to talk alot too - but now I have just learnt to type fast - eases the ears of my loved ones
Heh, my Mom kicks me off the computer because she can't stand the 'tippity-tap' noises anymore!! 
TEMPER!TEMPER!TEMPER! Both my kids could run through walls when their meds are wearing off. They love to argue their points, no matter what the subject...ie anything that is in this universe. Hatefull tone of voice......this really gets me.
Just when you think you can't take another minute...........they HYDE, and say " I'm sorry mommy, you know its the ADHD".
Gotta love em. 
Marge have you been in my house????
The only difference is Tynisha loves to collect rocks. I find rocks in the washing machine, in her jeans, in her bed, in her backpack, sometimes in my bed. I have enough rocks in and around the house to make a cobblestone walkway...LOL
temper??? you mean the fits of mental breakdowns that drive you insane? She also loves to debate and argue and won't stop until you just walk away. I usually pull out her coloring and craft stuff to stop it. Then she follows me around and natters non-stop to me.
AHHH the life of a parent of a adhd child.
Hi, My son is 6 years old and has ADHD. Some of his behaviors are the same as above, 1) Picks his nails constantly.
