Well, from personal experience, Id say Lowryder. I grow that particular strain myself, and I just love the high it gives. It makes me feel relaxed - note, NOT couchlocked - and also gives me just enough energy to babble. Its also a short lived high at around 2 hours, and Ive found that it only gives the munchies after the high has gone. Its also quite moderate in strength compared to other strains at around 10% THC. Sadly, I dont think MMJ clubs would stock this strain, so the only way around it would be to grow your own.

Im sure theres hundreds more strains out there that are more readily available though, and someone will surely give some input as to something that will work just aswell.
