benzos, soma, flexeral ect. will not cause water retention. everyone is a little to paranoid about water retention. nor will any of these hurt your condition or make your muscles soft. ive found soma to be very relaxing to the muscles and leaves the head perfectly clear, and does not make you drowsy. flexeral makes everyone sleepy. so for the night before flexeral as long as you get some kind of stim. in the am, cause it will leave you groggy, or ambian or any benzo will work, actually ambian is a weak benzo derivitive.
you should try one or all, (1 at a time)lol to make sure it works for you and your body agrees with it before contest time.
actually if its not the first time you have tried you can use a benzo on contest day and before night show. you would be suprised how effective this is for your nerves and if your used to the dose (ie. you are not a zombie) you will definiatly perform, and keep yourself composed better.
lots of bodybuilders do this. they"re easy to identify, they're the ones not pacing around talking a mile a minute and checking their physique way too much. lol. be careful, all of the above carry the potential for abuse.
