Hi all. This is my first Post, but have had this since I was a kid, I'm 26. What is everybody's recommendation for a guy who just wants to be able to take something on a rare occassion to protect from a bout of the D. I have pretty good control with using calcium and bulking agent. But I often fly on prop jets without restrooms aboard and I get concerned that I might have a shot of the D, and there is no bathroom. I was givin Levsin but I don't know if this works for D?? And if it does how should I exactly take it?? Would you recommend just taking a big shot of immodium in the morning before the flight or is there something better for a quick fix to combat a bout of the D (perhaps lomotril)?? I go weeks without problems, but get a shot of the D sometimes when I'm nervous (example when I fly on small jets). Any suggestions to this long post. Thanks.
