For Muscle Spasm "Definitely relaxed my back muscles. The only odd side effect is a very, very, very strong hangover. I couldn't focus my eyes on one thing for more than a second. Caused me to sleep about 18 hours at a time."

For Muscle Spasm "I had a breast augmentation and was required to take 10 mg 3x a day for the first few days after surgery. Never felt any pain. On my bottle, it warns of extreme drowsiness - don't know why this is such a shock to some. I ended up only taking 6 total and have some left over. It's been 3 years since my surgery, but I'm so glad I have some on hand, as I threw out my shoulder. Yes, it will either knock you out, or keep you up. You'll feel hungover either way. But it does what it's supposed to do; if you're in enough pain, it's worth the relief."

For Muscle Spasm "I took this when I pulled a muscle in my back and could no longer pick up my infant daughter. I took it in the middle of the day, and it helped with the pain. Initially, it didn't make me sleepy, but the next morning, it was near impossible to wake up. It was that terrible 'hangover' feeling. It was the worst I've ever felt. I could hardly make myself wake up to get dressed and use the restroom. I lay around until almost 4 pm the next day just because of pure lack of energy. Luckily, I was only prescribed it for a week or so, otherwise, I'm sure I would have quit taking it because of the drowsiness aftereffect."

For Muscle Spasm "I had right shoulder, arm, and neck pain for 2 weeks - I had taken Norco at night so I could sleep, but the pain was too much, and I had no relief. My orthopedic doc prescribed Flexeril 5 mg. I took one at dinner, but 3 hours in, still no relief - took a pain med (Oxy), fell asleep a while later - next morning I woke up and no pain - first time in two weeks! Since the pain meds had no effect, I know the Flexeril did its job. I felt a little 'hungover,' but okay - next night I took it alone, and I had no side effects the next day."

For Muscle Spasm "It was effective for muscle spasms, it knocked me out cold, though. The next day I felt like I was drinking alcohol heavily the night before. If you can handle the hangover, it is effective for back spasms...for me at least, as you know, medications are not one size fits all."

For Muscle Spasm "This was a difficult drug to stay on. I had what felt like a perpetual hangover. It did help with the muscle spasms, but not sure it's worth the 'hangover.'"
