muscle spasm
"This is my 3rd month on Tizanidine. Was on 2mg four times a day for severe low back and neck spasms and pain from an injury sustained while in Iraq. Also been on many types of relaxers and other pain medicines with no significant relief until my doctor wrote me a prescription for tizanidine. Since I've been on it daily activities have increased, taken 2-6  hour road trips with no major problems, and been able to increase my nightly naps and turn those into dream filled lapses in reality for close to 6 hrs/night! Cut Ambien use in half. Now on 4mg three times a day. The only negatives I have for this medicine is it doesn't last long enough, dry mouth is bad, dreams are sometimes too vivid causing nightmares, and hallucinations have occurred due to user error. Follow doctors orders while using this medicine."
