Welchol and ibs

Going into my second week and experiencing irratic sleeping, lower back pain, occasional nausea and a lot of gas. I'm taking it for IBS and to lower cholesterol. I have also been taking a probiotic and something called chlorella, which is supposed to be one of the healthiest, natural supplement on the planet. So I was thinking the combination of all of the above was causing this. After reading all of the side effects, I'm thinking strongly of quiting the Welchol. Will give it one more week.

All this talk of HAIR LOSS, POSSIBLE GALL STONES, ANEMIA etc. is really scaring me as my doctor (gastro-i) has prescribed it for extreme IBS. Am interested to know if anyone else has experienced hair loss. I HAVE been experiencing gas and feeling tired. Don't know if the tiredness is due to the Walchol. Am very uncomfortable about taking this drug after reading all these comments.
