Natural - or gassing? Big difference. For the naturals, the dropping of water is really not important till the night before - your body will take care of things by morning. Unless you are nervious as hell - in which case you should take something to relax or you will hold whatever water you have. The natural supplement you mentioned is great - use for 3 days prior to show / photo shoot. Here is the tough part - how much can you take in complex carbs to fill the muscles before OVERFLOW occurs? I would suggest you test it for your self the week before the event. I have come in better with cheese cake for vascularity, and a 10 oz sweet potato and a bunch of NO, without worrying about cutting water till 5pm the day before, and then still drinking some. Stay off the fats, but have small meals every couple hrs. untill 15 mins before the shoot when you want to take the pump and vascularity stuff. Does this make sense to anyone out there. Some one can explain the movement of carb glycogen into muscles better than I can - too little and you will be flat - too much and you will look bloated with water - but it isn't water - its overflow from too much carbs.
