Guest guest Posted June 30, 2012 Report Share Posted June 30, 2012 in your last paragraph you mention stimulents - are you talking about those used for ADHD (ritalin, concerta, etc) thr paranoia is the worst part of this for my mom... if they true stimulents help, I'll talk to her doc about them. is there an article describing the use of DLB that I csn read and bring with me when I talk to him thanks heddy > > Why such strong feelings about benzos? > > Simple: they're delicious with a couple of margaritas.
