I suffer a lot from nausea and severe pain and have always been on the look out for my magic bullet meds, and a friend gifted me sweet tooth #3 x ak-47 f6, 8 week flowering time heavy yielding indica, it stops my nausea in it's tracks, great for pain and helps me sleep and I'm a super heavy medicator. Blueberry, shishkaberry also help a lot with nausea. The sweet tooth #3 x ak-47 f6 harvested at 6 1/2 weeks really brought on the munchies, great for pain and insomnia, taken later at 8 1/2 weeks it was more narcotic, not as munchie inducing and great for pain and nausea.
I have a master kush coming up that will be ready to harvest in 5 weeks or so, but I've heard good things about it for pain and nausea.
Death Star is also really great for pain and insomnia, not so great for nausea.
Golden goat harvested at mostly clear/cloudy is very uplifting giggly, munchie town buds, taken more amber it's great for pain but also not as mood elevating or munchie inducing. I hope this helps a bit.
