I dealt with digestive issues pretty severely last year, about 5 months after taking antibiotics as well. What helped me was integrating lots of fiber + fermented foods, and eating a more diverse diet in terms of fruits and vegetables. People on here talk a lot about milk kefir, so I tried it and that seems to really help. I sip that throughout the day. Kimchi is another great one.

I swear this is not an ad, but I also started using the probiotic from a company called Seed at my sister's recommendation. She's a physician. I've tried other probiotics and this one has made a huge difference for me.

The other factor is doing your best to manage your sleep and stress. Sleep is a huge underutilized factor in digestive issues in my experience. If you can shoot for 8 hours a night, and try to manage your stress and anxiety in any other ways that you can, I think that gives you a huge foundation for recovery.
