Nausea and vomiting during first trimester

Hi ladies, #firsttimemom here at 10 weeks. Been having nausea since 6 weeks and gag everytime I try to drink water. The nausea got worse around week 9-10 and I gag more often but I always try to stop myself from actual vomiting. Wonder if you guys feel better after vomiting? Should I just let it out instead of suppressing it? Also, any other remedies to deal with the nausea and lack of water? I have tried drinking honey/ lemon water and 100Plus but always end up with a weird aftertaste in the mouth (I googled and seems like folic acid is the culprit here) :(
