I have just started taking ultracet today. I was prescribed 2 tabs 4x's a day. I have taken 4 tabs so far. The pain is better but the pharmicist told me and my partner to watch out for psychotic episodes since I am taking 20 mg of Paxil a day. SCARY!!! So far just stomach upset. But not intolerable. NO PAIN!! I have suffered from chronic pain for 3 years after I tore my scapula away from the muscle and ligaments. I do feel a little wired. I was also told it was non habit forming. I have taken morphine and loritab but cannot handle the withdrawl. I think 8 tabs a day is a lot. Let you know as the days progress. Especially about the psychosis. My Dr. was informed about the Paxil and said it should not become a problem. We will see.
