I'm still getting sick sometimes. A lot of times it will be out of nowhere. One day I was walking my dog out of the vets office, and all of a sudden I knew I was going to be sick. Luckily my DH was with me and held our dog and helped me feel better. I hoped that after 1st tri I wouldn't be sick anymore, but I still am. I'm still taking my nausea meds. I hope you start feeling better! Sometimes in the moment you can will yourself not to get sick, (I've done this in cars many times but as soon as I can get out, I get sick), but it will eventually pass altogether I'm sure.
Oh and I did start feeling a little better I think around week 16 or 17. I didn't just jump into 2nd tri and feel great. Good luck hun!
