I have never used methadone and take long acting morphine (Kadian) every 8 hours and percocet 10\325 2-3 x daily as needed for breakthrough which works well although oxycontin made me foggy at any dose...with Kadian making me feel very normal so all meds work differently for all of us and its trial and error to find what works for us! I agree most Dr's resent pt's asking for drugs by name although my pcp knew me as a nurse and trusts my judgement so I can get by with it with her!
