If you have access to it take some promethazine or if not, get some meclezine (Dramamine). You could also try eating something.
???Maybe a low dose of diphenhydramine (benadryl)???
If you took a whole pill yesterday and felt nothing, why would you think that taking half of one would do something?
If need be just don't take it. I'm sure you can do something with it, if ya catch ma drift.
What's the point in getting high if it's going to make you feel like shit?
I'd personally be sober and less uncomfortable, then slightly buzzing, and feeling like shit...maybe I'm just weird like that though lol.
Not all opioids are right for everyone. Some people can't take the -codones, some can't take the morphones, some can't take codeine, etc., etc., and then there's some that can't take any of them...Don't eat something if you don't like the way it makes you feel.
