oral lasix question

guys i really want to make middleweight sat, so i think im going to use lasix. i have one 40mg pill. if were to take half at around 12 fri, that would give me enough time to either take the other half or eat some food right? i probably will need to lose 4-6 pounds. i will also stop drinking at the same time. here are my questions......

1. if i do get what flat, what should i eat/do?

2. should take just take 40mgs at once?

3. should i supplement anything else? like potassium?

Don't use it. Most likely you would screw up your look.
Never use oral Lasix as it's very unpredictable and most likely you will not get the results you want, quite the opposite.
Only use injectible Lasix as it's very predictable - as soon as the injection is finished, you start peeeing and you stop 45 minutes later. Then you can asses where you are.

Generally with diuretics, especially with LAsix, this is how it works:
after the injection, you loose water from your vascualr system and muscles first. Then you lose water from under the skin. Many hours later, the water will return to the muscles and veins. Several hours later it will return to the skin.
You want to walk on stage after the water has returned to your muscles and veins but before it has returned to your skin. How long is that? It's all individual, that is why you should experiment with it way before your show.
Never use diuretics for a show if you haven't experimented with them first to see how your own body reacts.
