BIG MISTAKE. EXTRA LONG
It frightens me to hear what you were eating so soon after surgery. Mine was 4/18 and I am still on full liquids with a very few tiny bites of some mushies like hummus & mushed up soft cooked egg. Please back off and follow the plan. Sorry about the constipation but you should make sure your solution is something which protects your new stomach while it heals. This could have been very very serious. My surgeon says he has had a couple of leaks, and both times the patient were "non compliant" with the post surgery diet.
Glad things are moving now, but also remember you are on liquids so you aren't going to have normal bowels until you are on solid foods for awhile. There just aren't much solids to back up at this point so it may be a few days in between BMs. Hope things go smoother from now on. Glad you are healing and up walking, good for you!
