xpell(diuretic) and carb loading help please!?!

Ok so im trying to get ready for a river trip on memorial weekend (this saturday) and i need some advice on how to plan this..
I have been on a keto diet for 1.5 weeks now, no carb loading yet.

I have lasix(prescription) and xpell(otc). I think lasix would be a bad idea, especially if i have to float a 6 hour river in texas heat.

So i am wondering how i would go about using xpell and carb loading with it.
It is a natural diuretic that doesnt pull you potassium, so it is much safer. But it doesnt work as fast i think or as well obviously. You are supposed to take a week of it, 4 caps morning and night. Now the question is, if i take xpell right now would i still get the benifit of carb loading on it, will my muscles still get full? should i do a 2-3 day carb load before saturday like i would for my comps when taking lasix?
Need some help and direction please!!!??
remember im carb depleted right now with about 35g of carbs per day..

DO NOT take lasix. take expel to the MAX of the label recommendations from m-f. use normal water load/taper protocol & carb up depending on your weight/condition..

EDIT.......shit-just noticed that ur show may have passed... sorry
