It's still a very new pouch - whatever you're experiencing now doesn't predict what you'll experience over the next months and years.
That being said, there are things you can do that may help. You haven't said what you're already doing, which invites redundant advice, but I'll offer up some things that may help:
1) Even if you haven't been doing kegels multiple times every day for the past six months it's not too late to start.
2) I used Metamucil from the day I got home, with good results. The best dose varies from person to person, and some do better with other sources of soluble fiber (e.g. Citrucel, Benefiber, etc.)
3) I get better results from Lomotil than Imodium, but either one can help. I no longer use it during the day, but I sure did when my pouch was new.
4) Experiment with your diet, making small enough changes that you have a chance at discovering what, if anything, makes a difference. People have all kinds of diet suggestions, and they're often a good place to start getting to know what works for you.
Good luck! Things should start to improve for you soon.
