Just tried this over the weekend. Used Eph hcl, caffeine pill, probiotics, and Yerba Prima Psyllium.
While not as dramatic as Dsade says it would be (at least in my case), it was interesting to feel the bolus move around when I woke up. I'm surprised I didn't have a dream about being in an Aliens movie.
Results speak for themselves and it dropped my weight about 2 - 3 lbs. over the weekend. Not bad for something so quick.
As a tip, keep some instant coffee on hand just in case. I had to take a shot after waiting for an hour post stimulants. That seemed to do the trick.
