Still nauseous at week 12..when will this stop😪

From what I read online, most ladies start to feel better at week 10..though it definitely differs for every individual. I'm still feeling nausea all day, doesn't help that my work is pretty hectic. Feeling really sick of this already..I'm just hugging a plastic bag everywhere I go everyday. Tried Diclectin but always end up puking it out. I haven't been taking any vitamins as well as I feel unwell after taking them. Tried to replace with maternity milk but it makes me nauseous too. Quite worried that baby is not getting sufficient nutrients.. Mummies, when did your nausea stop?
