Taking 10-15mg Oxy 18 Days In A Row

(Pharma not street) I had previously used oxy for a month and had a fairly easy quit due to Megadosing Liposomal Vitamin C + gabapentin + valium. Had a relapse for 18 days and today I’m starting my taper with a bit of fear.

Should I have a reason to worry? I feel like I’m just a bit more tired than usual when I skip doses, but when it’s time to quit I get anxious. I’ll be tapering down to 7.5 today then 5 for about 2 days and then jumping off. I still have the triple team of vitamin C, gabapentin, and valium to help. Does that sound reasonable or am I going to be miserable?
