I went back after nearly 2 years clean. I don't recommend it. Once again I'm lacking in mental energy. I'm all for MJ if you need it, but I think a lot of us are fooling ourselves into thinking it's benign. Sure, it's better than alcohol, but I don't think that's a useful benchmark.
Sobriety can be boring, but until someone invents a better drug I think it's my only option until I retire.
