Lately, I've been sleeping all day, and eating a LOT a night. After I eat a ton of food at night, I start to barf-burp. Like, I guess it's a burp, but theres throw up coming up in my mouth. Is this acid reflux? I also have had constipation for many years, and I'm starting to think my constipation might be IBS. Does any of this connect at all?

Also, I've been in a depression and have been having mood swings for a few months now. Again, I'm wondering if all of this is connceted?
