I been on this for 20 years after having 3 back lower back surg, i was taking 4 morphine and 5 percocet a day with lyrica 150 trazadone 100 and ambien 10 I stopped everything but my morphine for a while until my mom got sick and i had to take care of her and hurt my neck. so I started back taking the percocet but I told my dr i just wanted to take bthem twice a day. How can i stop taking them all together and which one should i stop first Im tired of the way they make me feel
