Mallinckrodt hydrocodone pills, esp. the M361's are weak as hell and tend to make me more nauseated. Watsons are the best generic hydros I've had. One thing I've noticed, and this might only be me, but hydros or oxys with less tylenol give me less of a buzz. Watson's Lortabs (10/500) seem weaker than the Lorcet (10/650) The same for Percocet 10/650 vs Percocet 10/325. Whenever I come across OxyContin, I actually take some tylenol with them. Does anyone else experience that? I really think the tylenol (acetaminophen, APAP, whatever you want to call it) is synergistic with the opiate in the pill. So, to me, Watson 540's (Lortab) are weaker than Watson 503 (Lorcet).
