LOL I'm horrible on the eating end too. Don't really know how to cook and don't feel like wasting time to learn. I used have the worst eating habits, pretty much all my food came from vending machines or take out (fast food and real restaurants).
My main problem is I never realise I'm hungry until I am starving and then I need something quickly don't have the time or patience to prepare and cook a meal. When I try to plan ahead of time it feels like a major chore, because I have way too many other things that I could be getting done instead of preparing food.
I have found two ways so far to eat more healthy. The first is I will (try) to cook something big once a week like lasagna, pot roast anything that I could eat for a couple of meals. Since I'm only eating for one I could easily eat whatever I prepared in advance 3-4 times that week. I just pop it in the microwave or oven for a few minutes and have a real dinner.
The other thing I do is make sure I have plenty of small, healthy snacks that I can access instantly. I'm not a big eater in general. 3 meals a day is almost unheard of but I usually can get 2 meals in. I buy lots of fruit, granola bars, and salad. The salad takes a bit longer to prepare than the other quick meals but it's really not that long and you don't have to wait for it to cook (obviously) just chop up the ingrediants and eat. My current favorite to grab as a quick meal is a can of fruit cocktail for lunch. Half a can usually fills me up. Sure it's not as healthy as chopping a variety of fresh fruit yourself, but if I had to take the time to do that I wouldn't eat any fruit at all.
Can anyone give advice to solving these problems I have relating to ADD/ADHD.You should leave the med choice to your doctor. If you go to your doctor and say "I have ADD, I need ritalin". He may feel your just making things up to get med's.
You need to work with your doctor on finding what will work best for you. (Help the most with your ADD, with the least amount of side effects) Just taking a pill is not going fix things alone, counseling and learning new life skills can be a big help managing your ADD.
