muscle spasm
"I read through some of the reviews here and wow, what doctors are you seeing that prescribe 10 mgs, 3 times a day?! Of course you have side effects lol. That's jumping off the deep end. You always start low and ramp up. Make sure you google medications before just taking them. Doctors can be wrong and are wrong lots of times. 

My doctor told me 5mg to 10mg a day only at night. I'm on my first day after taking 10 mg last night and feel pretty groggy but I only slept 7 hours (more than I usually get). I took a 5 mg pill at about 10:20 pm last night and was laying down for an hour before I took another 5 mg pill at 11:20 pm. It was about 12:20 am when I last looked at the time. I did wake up with a headache that went away after an hour though"
