For the past year, I've been taking loperamide for stomach pain from anxiety. I just read a study today that peripheral opoid receptors are mainly responsible for testosterone decrease from opiates. Methylnaloxone a peripheral opoid antagonist completely antagonized opiate induced changes in sexual behavior. When I think about it, my libido has been low since I started taking lope and I'm also developing gyno. I was wondering whether there's any non opoid ways to prevent diarrhea and how long the diarrhea will last. I'm also interested in how long the other mild wd symptoms will last, when I tried to quit before I had goosebumps, restless feelings, and stomach pain.
