Any advice helpful

So I was diagnosed with hyperemesis gravidarum and I am taking ondansertron 2 times a day and occasionally cyclazine if I feel really bad but I have got constant nausea and u was wondering if any advise I'm bedridden as I can't sit in places that smell and I don't know if its healthy for baby. I can't even walk to the shop round the corner. My partner worries about me n baby not getting the exercise I can't cook for my partner anymore like I use to and I can't make myself food while he's at work I just need some advice to stop the nausea without having to go on tablets every 4hrs again. I want to visit my family this Christmas but at this rate I won't be able to. I am finding out the sex on Thursday and want to be able to get there and back without being sick...
