FYI, I went to the doctor yesterday and he said Flexeril is known to cause skipping heart beats and other problems like that and I have to go off of it tonight. So, I went off the Flexeril last
night and has some trouble sleeping but took an antihistamine and I seem to be doing ok today. So, far my heartbeat is better. I hope that does the trick. I looked up the side effects of Flexeril and <1% get the arhythimias and so I guess I'm in the 1% as usual.
