I have had IBS for many years. Typical symptoms of constipation alternating with loose stools. Have taken 1/2 dose of miralax every other day for years. 3 weeks ago I quit all carbs (except for vegetables). No carbs or sugars at all. I lost about 4 pounds the first week. Since then nothing. Also I have had extreme bloating and distention (actually this started about 4 months ago, but cutting out carbs has not helped. ) I also take a probiotic and recently started taking one with a prebiotic in it as well--twice a day, 20-30 minutes before a meal. Why am I having such discomfort??
