I was prescribed pain meds after a major surgery about 9months into sobriety. I absolutely needed them and I knew it. doctor was very clear with me how long I should take and it was just for 4 days with the heavy stuff. I felt slightly uneasy just like you. But I also knew it was necessary for pain control. If I wasn’t able to control the pain or sleep, who knows what I would have done. Self medicate maybe?
