Melatonin is a tricky one, in my experience. It is often dosed way higher than it's really ever produced by the body, so it's like OD-ing on a hormone. That doesn't sit well with me anymore since I tried 5mg at bedtime in second month PCS.

I read that in children, an overdose of melatonin can cause seizures. Well, I found that interesting, and can look back and see (after the fact) that I was having my most disturbing "seizure like" symptoms (burning smells waking me from sleep, grinding teeth uncontrollably even once awakened) when I was regularly taking melatonin. I know it works for some people with zero issues, but I thought I'd share. I stopped taking it because I felt it left me very foggy... But later attributed the weird symptoms that had gone away once I discontinued using melatonin.

I was prescribed amitriptyline (Elavil) for increased sleep, and to "assist" with some pain relief. (My best interpretation of that function of the drug is that it works on nerve pain and has even been shown to assist in new growth of nerve fibres) Someone feel free to correct me if I'm wrong there.

Long story short, Elavil works for me. I'm on 20mg at bedtime, but I find that it takes a couple hours to kick in so I try to take it mid-evening. May be worth bringing up with your doctor. Someone else told me that, but luckily my doctor suggested it on his own... They always seem to like their own ideas much better. Lol

Sorry for your insomnia. It sucks. I forgot to take my Elavil at the right time (I forget often... Another wonderful PCS symptom, no matter what reminder tools I use!) so now it's past midnight here and I'm up. Blah.
