Hi Stacerella, funny you mention brian chemistry and how it can affect us ADHDers.
In my case, drinking coffee too late in the day will cause me a great deal of difficulty in falling asleep.
In terms of food and what i’ve noticed has helped(with concentration), is eating lots of fish (Salmon, Shrimps, etc).
I ‘ve been prescribed Wellbutrin, but that didn’t make me any happier nor did it help with ADHD. After a few months, my doctor switched me to Adderall, and although the effects were somewhat noticeable, I felt the negative side effects outweighed the small increase in concentration. Needless to say, I ‘ve decided to stop the meds and live with my “gift” of ADHD and use it to my advantage.
Omega 3 oil capsules seems to help too,
Certain spices seem to aggrevate my ADHD. Its that noticeable, especially the irritability (as my wife likes to point out).
Please forgive my jumping from topic to topic, so much i want to say, just can’t seem to dump it fast enough onto the keyboard
