I just wanted to share what has been helping me so much recently-- Probiotics!
I am drinking 1 cup of kefir in the morning and taking a pretty serious probiotic at night before bed and I have really noticed a difference with stools. (I am still drinking Miralax at night but I found it wasn't really doing the trick some nights). I really recommend everyone at least try this. Kefir is so good for you-- just google it! It has even been said to help with anxiety. I'm going to be trying to make my own soon and I'm thinking things will improve even more.
I hope this helps someone!
