Bebekspor,
I'm similar to you. I go once or twice in the morning, once around lunch, once or twice in the afternoon, and once or twice in the evening. I'm lucky in that I rarely go during the night. I'm 4 1/2 months post takedown, and am still heavily affected by gas, though it's getting better. My frequency is higher when I'm at work, which is usually out of caution to go when I know I'll have time. Honestly, on weekends, I go far less frequently as I'm on my own schedule and just hold it.... Unless I eat something that doesn't work well, then anything can happen. The only other thing that still upsets my frequency is if/when I aggravate a hemorrhoid. That leads to a feeling of urgency and more frequent trips.
Mgmt, I suspect we have quiet mornings and busy afternoons because we haven't eaten all night. Our morning BMs are emptying us out almost completely, and have had a little more time in the pouch to have the liquid absorbed. After we go in the morning, it's going to take a few hours for new material to move through (the quiet time), and since during the day we won't sleep through some of the feelings that the new content creates, we go a little more frequently. That's how it seems to be with me, at least. Sorry if that's stating the obvious, but none of this seems obvious to me!
