i had the luck of getting some of the best Weed long ago. Im on icmag just to find it again.
I guess you sometimes smoke African Weed. I think this might be not the best for you, cause African can be pretty caffeinlike. Shure all sativas can be like that.
So, i now tell you what i think is better: Principially anxietyfree, kind weed. Sadly such weed is rare. If you find some Vietnamese, and Cambodian, it CAN be like that. I recommend Honey b - Barneyfarms. Many say he copies, i think it could be Cambodian-c99 from reeferman he sells as Honeyb. Its very dreamy, principially uphigh, but not very racy. Its dreamy. Its Very very good, like all becomes a Dream.. hahah
Also, get some pure Pakistani, Afghani. There is an old Paki Line sold on TLT seeds. They say its just a peacefull relaxing weed. Old Landrace lines , not hybrids is what i strongly suggest to look for. These are not making you think bad thoughts.
I wished i could recommend you pure Cambodian Viet, but its hard to find. And, yeah you cant smoke them before bed, cause you cant sleep then, BUT during day, the Paki at night, and i bet you preffere this to toays african Landraces, wich are mostprobably not oldschool lines, and ever were pretty hyper in nature. (probably northafrican could be ok if it HAS to be african)
