Thinking about shooting up instead of snorting

Both my boyfriend and I have been snorting fentanyl daily for about 3 years. Neither one of us get high anymore... Not at all for that matter. Granted, whenever I try to quit for a day or so, the WD symptoms become a whole lot to bear!!!!!!!! The sweating, hot and cold flashes, restless legs and no sleep the list goes on and on. I feel that if I'm going to spend $300/day to just FEEL NORMAL that I should be able to enjoy the stuff... About a month ago, we made it 5 days before relapsing and when I used I got the nodding and all over comfy feeling that I just love oh so much. So in light of that, I again, have always been deathly afraid of touching a needle. I'm very squeamish and I get nervous that I'll shoot up wrong. Maybe it's all the snot in my nose!? I blow it!! Why the heck can't I get high or even a little bit buzzed from rocks of pretty snow White fenny!?!? Contemplating shooting up but... Withdrawals will be worse when I DO actually quit r stuff. Ideas anyone? Anything that you think may help the stuff become more potent? Thanks for reading my all over the place rant!
