jackedup....
i would not do lasix....nor is the safest by anymeans!
i have 4 competitions under my belt, so i have a little expierence here.
if you want to use a diruretic, i would go with something that is potassium sparing. such as aldactone.
lasix in my opinion, w/out expierence is dangerous.
aldactone comes in 25mg,50mg,100mg tabs.....4 days out from your show, do 50mg in the a.m. and 50mg p.m.
do not take in any extra potassium, because that also can be dangerous.
safety first...go with aldactone.
good luck and god bless
