Hi Skywalker, When I first got IBS, I had extreme D. I can totally relate to the 911 call. There were a few times where I felt ready to crawl on the bathroom floor and die. It's a hard condition to deal with, especially when you have to work a full-time job. I feel for you.
The best way for me to deal was to snack throughout the day so that when meals come around, I wasn't not starving and more likely to eat things I knew were going to cause me problems. I was never an herbal tea drinker (I used to live on Pepsi!), but I must admit that I got used to the taste and now, I actually look forward to a hot cup of tea. The benefits are wonderful and well worth it.
