As I mentioned, for me it's really not euphoric at all.
When I need it like I mentioned I do .5mg x2/day.
The one time I tried to catch some kind of positive buzz off it I went with just under 1mg and just felt sick. I didn't vomit or anything, but was very dysphoric, "cloudy," and nauseous. Wasn't pleasant.
So I strictly use a Sub to prevent w/d.
I do have to add that one of my best buddies with 0 opiate tolerance was given an 8mg Sub by some jackass who didn't tell him how strong it was. He took it sublingually and was fucked up for a good 20 hours.
The point is, I know people say you can OD on Subs like anything else, but I don't really understand how/why. It supposedly has a ceiling effect on respiratory depression and all, and my friend's story seems to verify that. Proportionally to not having any tolerance for any opiate, 8mg seems like a MASSIVE OD.
Perhaps OD'ing on a Sub requires mixing it with another sedative, like alcohol? I'm asking because I don't know. But Subs ARE strong, even if the experience isn't positive, you will feel something. Like I said, the one time I took about 1mg with my low Oxy tolerance I was totally out of it.
