morning sickness and medications?

so i’ve been having really bad morning sickness the past few days, and i’m worried about my medications!

i take thyroxine in the morning as this is just my routine, alongside my vitamins and folic acid, but i find i’m throwing up within 30 minutes of taking them? i’ve tried waiting until after my nausea has gone to take my tablets, but i’m then either sick again or the side effects of not taking my tablets yet start to kick in!

should i be taking my doses again? or is 30 minutes long enough for the tablets to be absorbed?
