Hi - I'm new here - but wanted to make a quick reply on this post - I started taking 10 mg. of amytriptaline for neuropathic pain (transverse myelitis) in April. With in a week or so it seemed to really help my pain. I took it at bedtime and it knocked me out quickly. I was really drowsy in the mornings too - one day had to call in sick to work and go back to sleep until 10 am!
Also have been gaining weight.

Now - 4 mos. later, the sleepiness and the pain relief seem to be wearing off. I guess I might need to up the dosage, but I haven't talked to my doc. about it yet.
