So first time oxycontin unsure exact dose but felt overall good and warm in the chest (orange pill if remembered correctly). A couple years pass and 3 percocet(10/500) were tried and just felt sedated, pressure in head, and time went by faster. A few months later tried one percocet (7.5/500) and just sedated a little and time went by faster. A week later 4 percocets(7.5/500) were taken and felt nothing special just sedated... didnt even feel itchy but did want to vomit. Is this because of the apap? Not a pro on this subject but havent been able to find that same feeling as the first time.... Not even expecting it to be exactly like the first time but something in the ball park besides sedated and possibly nauseous.
