For Muscle Spasm "I got this prescribed after a week of constant back pain (I twisted my back). 10 mg 3 times daily. I took one when I got home from the pharmacy (about 12 pm) and proceeded to be out for about 16 hours. Five days later, I am still having sleeping issues, both getting to sleep and waking up at a reasonable time. When I took the one pill, the back pain was gone, but I can't afford to be sleeping excessively. I'll keep it on hand for when pains are keeping me awake and I can afford to get 16+ hours of sleep, but it's not recommended if you have to function on a daily routine."

For Muscle Spasm "Don't take this. Don't even think about it. Play around with Tylenol and Advil. This medicine's side effects to me: shortness of breath, fatigue, stomach pains-sharp pains, unable to sleep. I am drinking as much water as I can to take it out of my system, but I'm on the verge of an emergency room visit. Have in mind this is my first time. Sunday evening. 1 10 mg pill. That was all it took. Be careful. Extremely careful."

For Muscle Spasm "5 or 10 mg works for muscle spasms, but dangerous if taken during the daytime. Caused uncontrolled drowsiness, deep sleep, difficulty waking up, constipation, blurred vision, and sudden unbearable headaches, leaving me unable to function. (5 or 10 mg doses had the same effects.) Lost a new job just 2 months after starting due to not realizing it was this medication's side effects of blurred vision, migraines, and exhaustion. I was unable to keep up with the workload and didn't relate it to Flexeril because I had been on it many years ago when I was much younger. I tried to explain to my PCP, but some docs just don't listen. I have since stopped Flexeril, no more headaches!"

For Muscle Spasm "The side effect that made me stop it was severe reflux. I would wake up from a dead sleep, basically vomiting in my mouth and nearly choking on it. This happened nightly for weeks, and I just couldn't tolerate it anymore. It does help a great deal with relaxing the muscles (and for pain). I also get insomnia from this while most people get drowsy."

For Muscle Spasm "I was prescribed Flexeril in the emergency room after a week of low back pain with no immediate known cause, but they suspect that my back pain could be related to uterine fibroids. I was asleep within an hour after taking. I've also been experiencing insomnia related to pain. I woke up about 3 hours after taking Flexeril and was able to eat dinner while still feeling functional and able, and went back to sleep for 5 more hours. When I woke up, I felt a little groggy, but I have a lot of sleep to catch up on, and the grogginess seems to be fading away. After my first experience with the med, I will only take this before sleeping. My back pain has decreased to the point of being able to move around better, but did not take the pain away completely."
