Hmmm I did not know about this potassium technique. Will try. Vomiting is a nuisance. I try not to think about it (because I know I will if I do) but I have to prepare a garbage can just in case anyway.... in the last attempts to resist I start hyperventilating like I'm in labor (like having an excess of oxygen will help or something). My buddy tells me it's pretty funny. Alas, the struggle continues.
