I don't know if this question is within your scope of knowledge, but I am running out of time for an answer so I thought I would try. I have a contest in one week, and the only diuretic that I can get is lasix. I was curious if you know when to start taking it and what dosage. Also if you should supplement with potasium to offset cramping. The lasix that I can get is injectable not tab form. Thanks a lot!
