I also posted this on the pain management board -- I have a very MILD case of endometriosis, but occasionally it is severe pain, to where I can't walk without pain, other activities produce sharp stabbing pains, etc. The four OTC meds that I know of (aspirin, acetominophen, ibuprofen, & naproxen) did little. I tried Ultram 50s 2x a day and they worked better, but my doctor decided to prescribe me Darvocets instead. The dosage is a 100 mg propoxyphene + 650 mg acetaminophen tablet 2x a day as needed. Now, is this something to be concerned about as far as physical addiction? When I came home from work last night I did have mild abdominal pain but nothing that really need medicating in my opinion, BUT I felt sweaty and irritable until I took my evening Darvocet. I've only been taking them a for a week! Any comments are welcome.

OK this was on the directions: "Do not stop taking acetaminophen and propoxyphene suddenly if you have been taking it continuously for more than 5 to 7 days. Stopping suddenly could cause withdrawal symptoms and make you feel uncomfortable." Well I guess I answered my own question.
