Memory | ADHD Information

Anyone had any luck with a natural memory enhancer?  I take strattera and Concerta but sometimes I have the worst time remembering to take the strattera.  I always take it with food so I do not take it first thing in the morning.  I hate not being to remember small things too like appointments and such.  I have to post notes all over the place.  I am still kind of scattered even taking the 2 meds and not really keen on increasing dosages.  The best thing about taking the meds is that I sleep so well at night and wake up easy and do not feel like I need a caffine I.V. drip (but at 3 in the afternoon I could go to sleep at my desk.)I think not having good memory retrieval is the worst thing about being an adult with ADHD. It makes me feel like others see me as stupid. It has kept me from promotions more times than I can count. People just aren't stisfied with, "I will be able to answer that later but it may be 2 mins or three weeks" LOL
I wish I had some answers but I don't.
I will be watching this board closely, hoping there is something out there that will help both of us.
