Hi, I have been taking Nortriptyline for sleep, for about 6 weeks. Somedays I feel like its working other days I feel like I am getting worse than before I took the meds. How long do you give treatments before you try something else. This last few days have been really tough and I feel like I am getting worse! I want to get a sleep study done to make sure I am getting into stage 4 sleep with this med but I have a feeling the doc will say, lets wait and see "the proff is in the pudding" In the meantime I feel like I am worse on my bad days and better on my good days. Is this just nuts or what?
