I just read your post. I take flexeril for my fibro, but it is taken at nightime to help me sleep. I have read, (and my doctor has said), that one symptom of fibro is the inability to experience deep sleep. Are you taking it @ night or day? I take the same dosage as you, and it makes me drowsy. If you have to take it during the day, you may want to reduce it to 5. I hope you are feeling better soon. Take care of yourself!
