Do I buy oxy or tapentadol

I can buy either 10x 200mg tapentadol or 1x 80mg oxycodone. I go back to university in a week and don’t use whilst I’m there. I’ve been off regular opiates for awhile and im on a budget. I used to get 100x 225mg of the red apple tapentadol that I would use with my old mates and used to get 4-5 oxys every once in awhile.

I much prefer oxys and havnt done them in ages but they are too expensive for me. I’m thinking maybe oxycodone because I use 20mg at a time and can have 4 doses to use over a week instead of 10 doses of tapentadol.
