Milk of magnesia is what my surgeon told me to take for constipation. I have not had any problems with that at all yet so haave not tried it. I drink the EAS AdvantEdge carb control in chocolate & strawberry they have less then 1gram of dietary fiber in them. I get them at wal-mart. Best of luck on your journey!!! I have been on an emotional rollercoaster since my surgery too so I have been trying to stay away from everyone for now. Had a melt down a week after my surgery. It will get better, well that is what I hear, still waiting for that day lol... I was sleeved on july 18th.
