Sickness blues..

Jenna
Hey ladies.
I'm around 8 weeks pregnant and dreaded morning sickness has kicked in. It started off lightly with sickness early morning once a day. Now I'm constantly feeling nauseous and being sick. I can't eat, can't sleep and just feeling utter rubbish in myself and as a mother to my 5 year old.
Doctors given me cyclizine tablets but they aren't helping 😔 
Anybody else in the same boat or have an advice?
