I used both Metamucil and Lomotil (similar to Imodium) from the very beginning, and they served me well, though I was careful not to overdo either one. Many (most?) of us who've been successful went through a procees described as "stretching the pouch" - delaying visiting the toilet when the sensation of fullness starts. In the beginning you may want to be near a bathroom when you do this, until your capacity becomes clearer. Good luck!

Check with your surgeon before taking Imodium unless he already gave you the go ahead. My surgeon wanted me to wait a full two weeks before taking anything to allow some healing time. My two cents is start with the Metamucil. I always say not to take Imodium unless its really necessary to,allow your body to adjust on its own. Of course there will be times when you just need it. 

The wine could have definatley increased your bm's. Absolutely.  Your frequency will go down in the coming weeks as your body adjusts. Some people adjust quicker than others so it just depends.
