I had surgery on May 10, 17...I had small "gassy fart sharts" lol but it's been 2 days and I used my 1 year old daughters gentle suppository to help me go, I bought liquid colace...but I couldn't get it down. Thought about the milk of magnesia, wasn't sure if it was a stimulant or if it would be to harsh right out of the gate. I too am concerned about constipation but it's not like I'm eating solid foods, so why do you think our body should be putting out? Dr. Seems to think it will be fine and told me about the colace... just wanted to sympathize with someone else lol
