I have dropped my lamictal down to 200 from 400 to see if it would help ease my rash .... and yes I do feel different ... maybe not sharper ... but not quite as slow as I may have been .... of course I stopped the doxipen also ... so not sure what did what ... been on these psych meds for 4 years now ... yes I feel they have limited my social ability and my ability to form complete sentences .. of course I never was too sharp to begin with ....
