hi I was prescribed with 200 mg. of tridural for bad neck pain and bad shoulder pain.i ahave been takeing amitriptyline for years because I suffer from insomnia. I am a shift worker for 37 years. I take 100 mg. about 2 hours before bed. it does work but not exactly the greatest.i was told by my doctor to stop takeing the amitriptyline, cause they counter act with each other. don t know how my sleep will be? need my sleep cause my job is very physical. I slug about 8 to 10 tons of steel in a eight hour period. can you suggest something to get some descent sleep. while I try the tridural for my pain.
