Dude I speak from expierience.....37yrs and been smoking for 27 of them and if I smoke Sativa to this day I get paranoid and just the uneasy feeling called " ANXIETY" and I hate it and the only thing in the NATURAL world that cures anxiety is a Medical Grade Indica bud. This is what I grow and I tell you indica "couch lock " is the way to go. I don't smoke if I need to get up and mow the grass because the shit I have you will only make it to the cupboard to grab a box of Cap-N-Crunch a bowll, spoon and the whole gallon of milk! Then after about 2 hours when you finally wake up and realize you ate half a box of cereal spilled a half a gallon of milk on your carpet you will say to yourself......."Damn there was NO ANXIETY there now was there!!!!"
