For what it's worth, Zanaflex first knocked me out. But after a few months it no longer did, and I could do my work as a lawyer right through it: until I couldn't due to pain. I was up to 36 mg. [4 mg. x 6/day] for maybe 3+ years, before it stopped working and I was switched to Baclofen tablets -- now at 50 mg./day -- which I'm advised is the limit. It works pretty well, but plays random havoc with at least my short-term memory.

When the cramping gets really strong, I double down on Neurontin and take some Marinol, which is great except that it takes about 45 minutes to cut in and then leaves you stoned for quite a while: it being a synthetically created but exact copy of one of 6 naturally occuring TCH molecules. (And as noted a little while back on another thread, it can be legally prescribed throughout the U.S. and Canada.)

Something else to consider for spasms, in any event. (And I too take magnesium: a full gram every night.)
