Evening Nausea HELP!

Ok mammas! I’m 14 weeks and my all day constant nausea since 5 weeks finally subsided last week. I have occasional nausea some days but nothing terrible.

But almost every evening or every other evening I’m having serious nausea. I thought it may be because of not drinking enough water throughout the day but I’ve been chugging everyday and still some evenings I am out for the count with horrible nausea. Ginger pills, sea bands or anything have never worked for me. I did have a prescription from my doc for 2 weeks when my all day nausea was bad but I don’t think I need it for just this evening nausea. Any tips??
