OK, this is going to sound bizarre but I was at my wit's end.
My personal experience with Alli has been that even if I don't take it with a meal, if I have taken it up to 24 hours prior it still has some effect. Needless to say, this has caught me off-guard when I decided to take a 'day off' and have a nice thick ribeye steak. Despite not taking Alli with the meal, I still managed to get 'treatment effects' and wound up soiling a $150 pair of pants in the process.
After careful consideration, and being the inventive type, I came up with an idea. Butts aren't the only bodily orifice known to leak, right? And rather than re-invent the wheel why not use the time-tested solution? And so, I made the decision to try a tampon in my butt.
The verdict? It works...beautifully. Now I can fart without fear, even if I've been a little generous in my fat intake. The tampon soaks up the grease, letting gas pass on by.
Some of you might be noticing that I'm a guy, and so what the heck am I doing with a tampon. Seriously though, just think of it for what it is - a removable wad of absorbent cotton. Heck, when I played football we used tampons all the time for bloody noses. They worked great, and I don't think anyone is going to be questioning a sweaty football player's masculinity.
Side tip: If you're a guy that is shy about buying tampons, try the self-checkout at Wal-Mart!
Another side tip: Watch out when removing the tampon. They tend to be squishy and greasy. In a pinch, one could probably be used as an oil lamp :)
