There is a questionnaire on this site to determine what you are lacking, what is your dominant neurotransmitter etc.
I get alot of True answers for GABA. like i find it hard to find the right words. I hate explaining things to people. I have problems with recalling events.
I'd like to take something that the body will use to make any transmitter it needs, as i'm nervous about unbalancing my brain chemistry even further.
