Quinnatpeace,
Every time we go back to things like Oxy's, the longer it will take to feel well. You already have 8 days which is great. Build upon the time you have & before you know it, you will feel a little better everyday. keep attending meetings & definitely speak to your sponsor, or another addict that has a lot of clean time. I think you will find how they dealt with those feelings helpful.
Hang strong.
