Morning sickness

First pregnancy I suffered with really bad nausea, passing out and i slept alot which made me feel better, this time around im working full time and looking after an almost two year old while my husband works offshore. Any tips or advice for dealing with serious nausea and an energetic 22 month old . I'm currently 7 weeks pregnant so no I've got a few more weeks of this before things begin to settle 😩 .

I've tried ginger biscuit, lemon, nausea bands, drinking lots of water etc

Any help will be greatly appreciated 👍
