Im going to be honest cause I don't want to be the guy whos like "my friend...or this guy I know"

I recently found a source for some nubain, I don't have a very addictive personality and I thought id just try a bottle. I've used it b4 without and problems. Well anyway, I woke up really sick this morning and I don't know if its the flu, just really hungover or withdrawls.

I got my 2nd bottle of bain yesturday and b4 going out I used some then after I got home I used some and went to bed...this morning I woke up freezing, then sick to my stomach and threw up, twice in 2 hours....I've slept till now and I still feel pretty shi*y, severe headache and still a bit nauseous. I figured im going through withdrawls but im not craving any at all...and its been 2 weeks in between the first and this bottle. I did have quite a lot to drink last night and I also have a sore throat. Anyway, im scared and I don't know what to do. Any help would be appreciated.
