Yes. Eating proper meals that are about 50% carbs, 25% fat, 25% protein and relatively bland/not overly seasoned really helps the nausea for me. I eat very well normally (not so high carb, much higher fat), but for me the trick is to never let my stomach get empty in withdrawal. There is a short period where I can't keep anything down & am basically constantly heaving when NOTHING helps, but once that is past, keeping my stomach half full with food like buttered pasta, potatoes, toast makes quite a difference overall, though especially the nausea. Not eating & being dehydrated stress the body. Sparkling water helps me too.
