I am on the Fentenyl patch, 50 mcg. I was taking dulaydid, 4mg 3X daily. I have run out of dulaudid because I am transitioning from my neurosurgeon to PM. I don't go see PM for another week. I was on Dulaudid for a month. Could I be experiencing withdrawl even though I am still using the patch? I also take 350 mg Soma and 600 mg gabapentin twice a day.
