You sound similar to the way I was right after my takedown. I remember sitting at home the first couple of days worried there was something wrong because I would go so long between bathroom trips- and, like you, I would try to "make" myself go because I thought I really should be using the bathroom more than I was. When I think about
it though, I really wasn't eating very much at all, not full-blown meals, and you probably aren't either. Even now, 7 months post-takedown, I will frequently have days when I go in the morning, then don't feel like I need to use the bathroom again until 3 or so in the afternoon. The real "action" happens in the evenings for me (though I still only go about
5-8 times a day now.) As time goes on, you will be able to tell how your pouch likes to do things- and adjustments and changes will continue to happen for up to two years, my surgeon told me. Everything B'Dereh said is spot-on. I personally don't take anything to thicken things, because for me when my stool is more formed or thick, I feel the need to strain more than a slight push to pass it, and I know that's not good for pouches. So I trade straining with formed stool for some occasional butt irritation with looser stool. It's usually not a problem though, just with certain foods.
As far as the gas, have you tried Beano? I was taking that sometimes in the beginning (thinking I should go back to it now- been eating a lot of veggies and boy oh boy do they make me fart, haha.) It works better than GasX because it prevents the gas from developing in the first place, I think. When I feel gas trapped inside of me, I lay on my back and tilt my pelvis/hips at an angle in the air. This often helps the gas to fly out of me!
