"for the past 4 years this medication has been great to me. i was prescribed this because i have had horrible tmj. at night this would ease my pain. it would also relax my jaw enough to sleep and not have clenching and grinding. i&#039;ve only had 2 problems taking it. it has gave me nightmares and it makes me so sleepy that i rarely get out of bed on time the next day. but all in all it has helped me."
