HI Gary,
Forgot to say, I did have night sweats a little while back, but not how you describe. I was prescribe a drug called amitriptyline, it is often used for depression in higher doses, but I was given a smaller dose for nerve pain for a problem I have had for some time. Whilst taking this drug, I had horrendous nightmares, which meant that I woke up in a state of shock with my heart pounding and clammy skin. I googled the drug, and found that it can be a side-effect, so needless to say I don't take it anymore.
I notice that you are on anti-depressents, check the possible side-effects of the drug, if in doubt go back to your doctors and seek further advice, but I wouldn't stop any medication without first talking to your gp.
