I had been taking Flexeril for 20 years to help me sleep and it stopped helping me a year ago. GP put me on Amitriptyline 10mg a year ago after a couple weeks it started to help some but haven’t gotten much more than 4-6 hours of sleep most nights sometimes 7 hrs. GP tried upping Amitriptyline but I got weird side effects so dropped back to 10mg..GP added Melatonin 5-10mg a couple months ago helped for awhile but now I go nights with no sleep to 2or 4 hours. Anyone else’s have this issue?
