Does anyone know how long you let it go on for before taking (or getting from chemist) some stemitil or bucostem etc? It's only been 8 hours for me, the cramps are unrelenting! Can keep tiny amounts down for about an hour and then it all gets too much again. Feel worse cause I need some fuel but the thought of it, blah. Currently sucking on one raisin every ten minutes and sipping sugar and salted water. Please make it stop!
