I wouldn't put my hopes on Contrave. For me Wellbutrin reduced my appetite for a relatively short period of time only. And the way that naltrexone works is as an opioid antagonist, meaning it is supposed to reduce your cravings by essentially nullifying the high you get from taking them. It seems to me that the way that could work is that you train yourself to remember it's pointless to take opioids because you won't get enjoyment from them. I don't see how applicable that is to food. You're going to be eating whether you want to or not. And food is still going to taste good even if you don't crave it.
