The morning sickness. I can’t.

I’m a mom of 3 boys and pregnant with my 4th and final little one. So, this isn’t my first rodeo…BUT I’m only 10 weeks in and this is my far my worst first trimester ever. The nausea is debilitating and I swear this baby is giving me IBS. Like I feel like I’m never not in the bathroom at this point. Anyone have any tips for how to curb the nausea so I can get a decent meal or 2 in and then how to keep it from instantly digesting and coming out the back end?! Sorry for the awful imagery but I’m at a loss.
