Hey Farmer,
Yeah you know, cannabis is one of the better medicines for this. Here is where a High CBD strain might help. Gives almost no brain effect, but a sever calming effect, (IMO). I know a few strains like Sweet N Low, where it was grown for the psychological effects for use on Schizoprenia (sp), and epilectic seizures.
If you do a search, you can see research in those areas ad the cannabis they are using. (this strain (SNL) is not publicly available, as far as information).
Look for somehting Indica-ee, with a good cbd count. IMO
Look into diet as well. We overlook what eating does to ourselve mentally. Look at Roots "eating your medicine" thread.
bye for now
Eek
