Withdrawal Symptoms

Started using after years of pain pill addiction. Fentynal was the first I ever banged unknowingly. Ive been to detox 3 times. Always sick within 24 hours at most. I went to a doctor and prescribed subutex. Its been over 30 hours and no withdrawal. Ive taken no subutex and my last shot was small yesterday morning. Ive used 3 grams a day since my house sold. I used to the point I couldnt get high because my tolerance was so high. So I thought. Im wondering if I was given fake dope at this point. I should be sick and Im not. Could it be the amount I was using.is built up in my system and taking longer for the withdrawal to begin. I dont get it.
Has anyone else taken this long to be sick. Im waiting for the worse to begin and I dont get it. My partner who used with me daily the same amount isnt sick either. We wer e doing half gram shots and not feeling it. But we also used cocaine and meth at times and thought it was due to that as well. Any thoughts appreciated. I would be so grateful if I dont get sick even though I spent thousands with my dealer.
I would tell you to count your blessings your not having withdrawal symptoms and continue to get clean. If you use again you might not be so lucky.
U should be thanking your lucky stars man....... Although I would imagine by now u are likely feeling quite differently..... Subtuex does last a while..... and u might have a build up internally that is holding you over. I wish you the best my dear
