Ill tell you my situation..... I was in full withdrawal from fent but didn't know what PWD were, so I was eating an m30 and then later taking a sub or the exact opposite. What it did was end me in the ER cause I was in such pain that I couldn't take it and they had to give me morphine. They never knew I was withdrawing becuase I never told them and I don't look homeless. Anywho I didn't feel very good for a couple days and I had just moved for a job which o hard to start as I was WD from fent. I remember coming home one day when living in a hotel trying to find a place to live and I took a sub after work and remember feeling 10x better rather then before where I was VERY sick. That was 72 hours after my last dose of fent......48 after my morphine injection at the ER, yes I got the warm rush B/C I dint IV or snort so that actually was enjoyable and can understand why people IV shit.
I ended uo back on the fake m30's and had to switch to oxy and have been stuck on real oxy for awhile but I SWEAR my withdrawals from a 160mg a day habit makes me go to the hoatpital now and its just as bad as when I first got the PWD... YES it makes no fucking sense, I wake up in the middle of the night sweating feeling sick to my stomach and I take 40mg oxy to make it go away and that's just to feel normal. I got outta the er after my puke fest and had to take a hydrmorphine and snorted it cause I couldn't hold it down, I ONLY snort when im in such withdrawals I cant eat it.... THE WORST but I use to NEVER get physical withdrawals but I also haven't been on this shit this long before.
I WISH YOU THE BEST but the best advice I can give is DONT pick it back up and one u go through the WD don't go back, I gave a HUGE job interview in a couple days for the biggest career move ever, I mean seriously ill be a senior scientist at a large Pharma company with 5-6 people working research underneath me... but I have to take my oxy and have it on a higher dose to perform for this interview, after it, if they offer me the job, I QUIT cold turkey NO SUBS and its gonna suck........ don't let drugs/the rush ruin your life and opportunities, I have many time and I won't let it happen for this one.
