I had a tonsillectomy on Thursday (4 days ago). Duh, I was expecting the recovery to be very painful and it is, but it's tolerable. I was given liquid lortab which I'm supposed to take every 4-6 hours. The first couple days was fine, but now it's like the stuff only works for about 2 hours and I already need another dose. I don't want to take more than prescribed because a) I don't want to cause liver damage from the meds and b) I'm almost out anyway. Any ideas? Should I call my doctor for more or for something else?
