Yes, Flexeril is a VERY powerful muscle relaxant... Took 2 prescribed low doses, and it ended up adversely affecting my balance for about 2 days... Went to the ER, they transferred me to Hopkins (idiot ER doc suspected Multiple Sclerosis...) got spinal taps, MRIs, CT scans, and everything, but it was all the Flexeril.

Now I can't take it anymore, too bad, because I really enjoyed those 2 doses :P

Don't mix Rx meds and cannabis... It won't be the cannabis that fucks you up, rather, the Rx meds will do you bad. That's kind of a legal paradox o_O
