Okay that certainly makes it different. I have been on a medical hiatus for about two months and am just making my way back. Normally people taking this are taking the Vivitrol injection. If this is happening my best guess is that it is all in your head, but I can not be sure, just use occam's razor. And assume it has the same duration as Vivitrol, then once a month is up try going back to the usual. Actually, Fuck all that. Just cut that shit out of your life while you still can. You are not feeling any euphoria from Opiates any more? Lucky fucker. Get out NOW.
