I had it only a few times and i wasn't nauseous, but the vomit came on real fast. I was trying at 1 point just caffeine pills and I'd vomit them - screwed up electrolytes - and brought on chas fast & bad.
Now ? I try to keep saltines and little kid graham crackers and if i start to feel even a little bit off stomach wise i try to get something in fast and that seems to help. I also try to even everything out, including food. And thats rough, for me... i normally prefer 1 meal in evening but now i try to have brkfst, snax, and dinner - at least. I just try to keep everything across the board stabiluzed. Its just where I'm at. Seens to help me.
