It’s weird how medications can affect different people very differently.
I had cervical stenosis and was on oxy for
14 weeks. Was taking 4 a day the first 2 weeks and down to 3 a day after first shot. 4 weeks later had a second shot as they localized the area and was down to mostly 2 a week, if I had a really busy day might be 3, a really light day 1. Still had some pain but it was tolerable.
Didn’t drink the whole time. Never had a buzz, never had hallucinations. All I had was less pain so I could function. Talked to a army friend at the range and he had the same experience. It really does affect people differently.
