Flexeril= CYCLOBENZAPRINE, not cimetidine which is used to cut down stomach acid secretion
You're absolutely right - I also take cimetidine (Tagamet), which is why I confused the two (when you get to be middle-aged and have been on these drugs for decades, they all start to run together in your mind, what's left of your mind, that is ; ^ ).
But thanks for noting the correction in case anyone might be considering asking their physician about the drug. Cyclobenzaprine (Flexeril), IMHO, is a miracle drug and has probably saved my life as well as my sanity, and aside from the obvious sleepiness, has very few side effects.
