ibromyalgia
"Experience chronic  neck/upper body muscle tension after 3 cervical surgeries including fusion w/ plates (c567) &amp; Artificial discs (c3&amp;4). Have disc issues w L5- S1, too. Also diagnosed recently w/ fibromyalgia (but probably had it for many hrs prior).  This drug relieved the chronic pain of muscle tension (spasms, knots) . Took 10 mg at bedtime initially. Best sleep ever but I could have slept 14 hrs! I woke up very drowsy. Instead take only 5 mg early in evening. No other side effects.  I take only as needed as a precaution."
