Gramps is right, though. Even 30 mg/day of lortab is really a pretty low dose of pain medication. Lortab is one of the more mild medications, so you are very fortunate that it is helping you so much. Gramps is not the first persona I have heard say that surgery has only made their pain worse. That is very reason I have been trying so hard to avoid it. In your other post, it sounded like maybe your other symptoms will be relieved with continued weight loss. If that works, perhaps you won't have to consider surgery.
I am sorry to hear you are feeling so poorly. I hope they can find a good balance of pain medications for you soon.
