I have suffered from IBS for 8+ years for the last 6+ years I have random "flare ups" with horrible stabbing pain with gas and usually diarrhea. I've never been a constipation sufferer really, always having soft to very soft movements 2-6 times a day on average without the "flare ups". I've been on the medication for 4 days so far, but take it when I wake up and wait at least an hour before eating and within 20-30 minutes of eating I am in the bathroom with liquid BMs for the remainder of the day. I have been purposely not drinking anything much to avoid the liquid BMs the most relief I've had from my usual symptoms is no cramping, but I'm still having the stabbing pains in my abdomen after the BMs. I just want to know how long I should keep trying this medication.
