I also initially was loving that opiates helped with my depression. I even asked the psych I used to see why not use vicodin for depression?! That was in my early 20s and I just started opiates, prescribed. Well here is the deal: Yes, they do help greatly with depression for awhile. However, over time those opes are ruining your dopamine receptors and other brain jargon. Point is, they eventually make it basically impossible to be happy, be interested in anything, and your depression sky rockets. That has been my issue for the last few years. I didnt know that stuff happens. One example: I used to eat, drink, breathe college football. I lived for that season. I was up at 9 am on Saturday and watched games til they ended. Well a few years ago I couldnt give 2 shits about it. I am the same way today. I'm like that with everything. It is horrible! I decided it was time to start weening down. I tried cold turkey but couldnt do it. But I am tired of life sucking every day. I hope I can get back to who I was. Even when you quit opes, it takes quite some time for the brain to fix itself.
So that is my heads up warning. You can find all kinds of research about it. Wish I had found it LONG ago.
