MMJ works for some, not for others.
Street variety (not legal around here) - Sativa
makes me intensely aware and increases my pain,
then makes me hungry then sleepy.
Maybe good for evenings or bedtime but not for work-days
and working with power tools.
Maybe if I had the luxury to try a year's worth
of 50 different strains (one a week?) I might find
that some Indica may help, but that's a pipe-dream.
