Working during early pregnancy!

How many of you mamas are working as a CNA or nurse? I am currently only 4wks + 2 but Iam already experiencing horrible morning sickness only at night! I work the night shift as a CNA & lately it's been so hard for me not to run to the bathroom every 20 minutes feeling like I have to throw up. Let alone I can barely keep myself awake for my entire shift. So my question is do any of you ladies have any tips that worked for you during early pregnancy while working the night shifts a CNA and or nurse? I would greatly appreciate all advice ☺️
