@angepange1 so sorry to hear this. I can’t help much as I’ve been so lucky with my side effects 
. I would definitely endorse asking for different anti sickness meds and skin treatment. There are many different ones they can give you and we must ask for them. Also have you tried ginger? Not just teabags but ginger shots (Sainsbury’s has a bottle of 7 ginger shots in its chiller section on offer atm). Anything ginger really. The other thing is if you can’t keep anything down at all and are not getting nutrients that you need you can try something like Huel (which I can’t comment on as never had it) or for a cheap and easy option Complan. I know it’s a different situation but when I was pregnant with my son (26 years ago!) I was sick several times daily, lost over half a stone and was only days from being hospitalised. I started drinking plain Complan and it helped me turn a corner. It’s cheap and easy to find. Just a thought. Really hope you start feeling better soon
