i am dealing with first trimester pregnancy nausea but it sounds a bit similar. both related to hormone levels. for me ginger tea helps a lot but so does exercise. exercise is supposed to help regulate hormones. when the nausea gets bad i have gotten on the trainer and ridden for 20 minutes and it helped. then i started having spotting and got afraid to exercise we found out the cause and so far my baby is fine and exercise is supposed to be safe but i am still anxious about it.

ginger tea really has helped me. also a lot of women dealing with pregnant nausea use unisom and vitamin b6 which you could google not sure if it works for perimenopause but might be worth looking into. if it is really bad it seems to me a doctor could prescribe something to help pregnant women who have really sever nausea take stuff to help deal with it.
