muscle spasm
"I've taken Flexeril off and on since 'late '98 when I was (mis)diagnosed with muscle-spasms (ER trip was due to a kidney stone). Flex was great at relieving muscles spasms for 7 out of 10 days Rx-d. I took it for all 10 days, tho' the low-back spasms were gone after day 7--the kidney-stone-pain, however, remained.



I've been taking it "as needed" (having fractured my T12 or L1 vertebra when I was 8, herniated discs, etc--at this writing, I'm 59) for about 6 months, per my PCP. After the first bottle, I told him about the soporific/zombie effects and he now requires me to take it only when I go to bed to sleep.



Flex has a 1/2 life of 18-23 hours. Thus, it doesn't wear off fast. A bit of Melatonin helps me get better-than-zombie sleep. :)"
