I am a 39 year old male and I have had symptoms if IBS for the past 18 years or so. I went back and forth between constipation and diarrhea and had zero predictability. It was at the center of every decision I made about work, travel, eating, etc. About 8 years ago I started taking Citrucel daily, at the suggestion of a gastroenterologist friend of mine. His words that "a full system works better than an empty one" proved to be very true. After 3 miserable weeks (he warned me), my system got adjusted and it made a HUGE difference. I am by no means cured, and I still constantly factor my condition into decisions, but it has been a major improvement. So, here is my dilemna. I am going to Japan on business in a month. The key with Citrucel is to take the same dose at the same time EVERY day. If you miss a day, you will be miserable for the next week or so until your body readjusts. Japan is 15 hours ahead of where I live (central time zone) and the flight is 14 hours. Does anyone else take Citrucel and have any suggestions on how to handle this trip? I need a plan for adjusting my time to take the Citrucel to accomodate the time zone change, and my own body clock adjustment to those changes. I went a few years ago and had a rough time and I want to avoid a repeat of the last trip if possible. Any suggestions?? This is my first post and I am looking forward to talking with others who are in my same situation. Misery truly loves company.
