@NelliePledge, this is a digression, but have you tried Sominex (which is phenergen, the antihistamine)? I have found it very effective. You can get it over the counter in the UK. My other half is over there at the moment, and always brings me back some. I'd start with a half tablet. A full one can leave you feeling dopey the next morning. I have also tried replacing amitriptyline with nortriptyline, and found the nortrip to be less effective than the ami for sleep. In general the tricyclics seem to be rather ineffective sleep aids, and being psychotropic drugs, I'm not sure they're worth the risk just for the tiny sleep benefit. I do worry about doctors' eagerness to ply us with psychotropic drugs - I don't think its because they work all that well for sleep. I think its because deep down, they think we are messed in the head and that's why we can't sleep.
