I've been given Amitriptyline HCL to help with my insomia and depression problem. I really love this medication but the problem is that I get use to it. I started at 25MG but after 3 weeks I had to up the dosage to 50MG. After a month at that dosage I'm getting use to it again. Although it still somewhat helps with my sleeping problem I find that I'm even more depressed in the daytime then I was before taking it. I was wondering how high of dosage can you go and won't I just get use to that dosage as well? I've tried several other medications just for the depression problem but after taking them for afew weeks I get use to them and it actually makes me feel more depressed as well. I try to tell my doctor at the VA that I have a problem of getting use to medications but they don't me even though I told them about my friend that has to rotate between several medications because he has the same problem.
