I tried Ami and other tricyclics, and other anti-depressants also - mostly for muscle pains and bad headaches but also for psychological symptoms. I reacted badly to all. Didn't help at all with pain, made me very 'stoned', didn't help with depression or stress/anxiety. Did make me lose all sex drive and ability to have orgasm, make me 'hyper' at times and definitely the other side of drwosy - didn't sleep at all for a week once. Certainly wouldn't take them again.
But I also didn't react great to gabapentin (for headaches) and the other preventative drugs for migraine did nothing.
I take sumatriptan for headaches and linked neck/muscle spasms as and when they happen plus used to take a muscle relaxant and opiods. All got 100% better (gone nearly - as did the anxiety/stress etc adn the need for the drugs) when I started taking HRT, came back when I stopped. With hindsight, 10 years of pain and self-destructive moods (etc) were definitely hormonally-related...
We all react differently and what works for some doesn't work for others. You can only try. Good luck whatever you decide.
p.s. the anti bed wetting is the same kind of mechanism of action/body system that causes the dry mouth. It might help you.
