I had my cholecystectomy about 4 months ago.....and for first few weeks had similar symptoms. When I called my surgeon about this, he advised me to eat small meals, throughout the day, maintain a low, or non-fat foods diet, avoid greasy, fried foods.....and basically keep as bland, as possible. of a diet.....for several weeks, and slowly return to normal diet as my symptoms improved.
I did follow that.....and am pretty much symptom free, and back to normal now.
