which variety of rcs are you using?
rc is just a broad term....
really not much makes them different from the other tryptamines and PEAs other than the simple fact that they have not existed as long or had as long of a period of human use.... after so many years of use, the nausea component doesn't just dissapear....
hell there are rc benzos, cocaine analougs, quualude analougs, an MCAT analoug, PCP analougs, and a pretty large assortment of tryptamines and PEAs that fall into the catagory of research chemicals.....
but some drugs just have a nausea component.... generally you will feel better after you puke. if your hardcore wanting to avoid it, try a little bit of pepto about 20 minutes before ingestion, or plug them....
i hear ginger is really good for reducing nausea as well....
