I took half of a suboxon (sp?) pill that I was given to me by a friend to help with a Percocet addiction. Approx 20 min after it dissolved in my mouth I started feeling very dizzy, very intoxicated , sleepy but also anxious and chills. I am not sure what the dosage was but it feels too strong. One of the reasons I want to stop using Percocet is because my BP has been very erratic. I have a history of high blood pressure and it is 150/110 right now (I take a beta blocker and lisinopril). I am concerned at how strong the dose feels and what I should do. My doctor has no idea about the Percocet or the suboxone. Please advise.
