I'm very glad to have found this site. I have debilitating IBS that was brought on by antibiotic poisoning. I believe there is a definate link between antibiotics killing the good bacteria in the intestines and IBS; hence my name.I've had to take antibiotics twice the past three years, and both times I went trough about eight or nine months of severe uncontrolable antibiotic associated IBS. Furthermore, I've gone back into my medical records and found that every time I took antibiotics I became unusually tired for months afterwords, even though I did not show IBS symptoms. As I've gotten older, I'm 42, the IBS symptoms have gotten worse.I also have a history of stress related digestive problems: bleeding gums,ulcer,heartburn, ect. But I don't have those problems now, which is why my doctor ruled out Chrons disease.I took Flagil immediately after taking the antibiotics and got some relief; but the IBS retured to make me miserable afterword. There was no way I could keep taking Flagil, so I started using DANON Vannila Yogurt, with very little real success.My theroy about my condition, after looking into antibiotic associated IBS, is that the bad bacteria damage the walls and the nerve endings in the intestines, bringing about IBS. I've tried numerous diets, and have had the best luck sticking to the Celiac disease glutton-free diet. I no longer drink soda pop, or fruit juice unless it is very watered down. Right now my diet consists of brown rice and chicken, vegtables, and iced tea, with a few drops of lemon juice; but I do not overdo the iced tea. I eat the same boring meal over and over again; but it's better than the alternative.Generally, for me an IBS attack is triggered by eating the wrong food or being under stress, or no reason at all. I get two or three days or possibly three weeks of runs, followed by weeks or months of constipation. Most of the time I am constipated. I take Citricel or Fibercon, because these fiber supplements do not contain flax seeds. Flax seeds, and any seeds in general are bad for the Celiac disease diet, which is why I can eat tomato sauce but not diced tomatoes. Even though I do not have Celiac disease, the diet works for me. The seeds irritate the walls of the intestines, because they get into the cracks.The interesting thing about my version of IBS is how tired and sleepy I get. I don't eat big meals because they put me right to sleep. I have a difficult time eating breakfast, because I'll eat breakfast and fall right back to sleep, so I drink Boost energy drink for breakfast. I then have about four hours before I start getting tired. I eat lunch and take a nap for a few hours. I get up and eat a snack and I'm good a few more hours until dinner. If I'm having a good day I can make it from dinner until bedtime; on other days I need to take a nap. Then when I finnaly do get to bed I sleep anywhere from 10 to 16 hours.I also have very little mental energy, drive and pep. I have days where I get very little done. I have days where all I do is sleep.I'm completely unreliable; not just when I go to the bathroom. I have to allow myself double the ammount of time for me to accomplish something, even then I can't be relied upon.I have to take time outs to avoid stress, I have to distract myself for a few hours now and then.I'm at the point right now where the constant constipation is putting pressure on my lower back. I have times where I can barely move from the back pain.I hate having IBS. I know how hard it is to try to control it, to understand it. I hope to visit this site frequently to help others, and to learn more about IBS.Good luck to all or you trying to manage this condition.
