It's going well for me. I had my reversal in mid August, after having the ileostomy for 10 weeks following my LAR and colonic J-pouch construction. The first month was kind of rough, but I got through it with pain meds (percocet) and Calmoseptic cream. The meds will suppress the rectal cramps, allowing you to get through 4 or 5 hours without problems, while the Calmoseptine sooths the inflamed tissue around your anus from all that crapping.
After one month, my situation was very manageable. Now, two months out, I'm really doing great. Currently (as predicted by my surgeon), I'll go 3 or 4 days without much happening (that's good!), followed by a "dump day" when 3 or 4 days of accumulated material is expelled over the course of about 24 hours (not so good). My doc (who hasn't been wrong yet) says that eventually this will settle into a 2- or 3-movement a day routine, which will be fine.
Milestones for me were: The day I got my "push" muscles back; the day I was able to differentiate gas from solids, and vent accordingly.
