I've used Lomotil, as I have crippling urgency and frequency being my most troubling aspects with "my" Crohn's. It had worked about as good as the double dose (two 2mg tablets) of Loperamide, or maybe a little better sometimes. The thing is that they're Rx, so they're a bit more money for "ongoing" applications, long term, and since Loperamide can come in 400 pill double bottles from Costco, I just get them from there and have used them for a while to save money.
Nice to see a cop around who has Crohns, not that it's nice you have it, but nice that your existence is known to me. I have police training guides that state it is very hard to become a cop with IBD, and that the diagnosis alone can keep you out of the running. It was very disheartening to read that and read the kind of issues that bar you from even being considered. On top of that, the mere fact that I take OCD medication worried me as well.
