Go back to your regular IF schedule (if I eat late, like on Fridays, I just make sure to get 18hrs in before I eat the next day), lots of water and get a good walk in if you can, will get everything moving along
Personally, I wouldn’t worry about the bloating too much unless you’re in serious pain and need to see a doctor. I always get bloated after having pizza, especially when I haven’t had it in a long time. My bloating from pizza usually calms down by the next day. Maybe have some herbal tea for your stomach to help it along.
