night time sickness?

i had pretty bad sickness throughout weeks 7-15. now i have nausea every night right when i’m laying down? i’m 30 weeks. is this normal?? i feel like if i get up i will throw up everywhere and i just shake my leg to make myself relax and not feel so bad. but i feel absolutely horrible, all day i’m fine but right at bed time i feel weak and disgusting. just so nauseous right now, hope this isn’t until the end.

can anyone relate?
