My pain Doctor has changedmy pain meds. and I am not sure how to handle it without going into withdrawals. I've been using Nalbuphine-1ml twice a day up until the past 2 days in which I reduced the doseage to .5ml twice a day. My Dr. told me to stop the Nalbuphine and begin taking Percocet 10-325 in 2-3 days. I'm concerned I will go into withdrawals during those 2-3 days. I don't know if this is the correct way tochange from an opoid antagonist to just an opiod. I would greatly appreciate it if anyone knows the answer, please post it or e-mail me. I'm very confused, worried and just don't know how to handle this change. Thank You!
