I hope you do look into a
detox facility and get some help to do this.
Coke and opiates are a deadly combo.
Coke cravings are different from pills as you know, they are so so much worse and scary and without some support and aftercare relapse is very common. Come up with a plan on how you want to get clean, it takes commitment, but worth it. Although I did use pills here and there, they were never my thing, cocaine took me somewhere i did not know existed. Congrats on 8 days clean from coke.
