I took Elavil ( amytriptyline) for 10 years. It was a total miracle for my migraines which I suffered with since age 8!!! . I was on 50mg and am a tiny lady. I slept like a baby, had no more aches and pains- it was amazing. Then after ten years I started passing out so I had to stop it. It was the best drug for me till it wasn’t. One pill at night before bed. As an elderly lady Medicare doesn’t like it now as it can be problematic for old people. I was put on just a small 5 mg dose a few years ago and couldn’t get my act together all day due to fatigue. That pill worked so well for for so long - I think our bodies change like every ten years or so. I miss it and wish it could work the way it did when I was in my 40’s.
