Horrendous morning sickness- PLEASE HELP!

Hi ladies, my morning sickness is absolutely horrendous! I wake up and I’m already feeling sick then I’ll get up and I’ll throw up or just feel so sick that I know I will be sick any second so I can’t do anything. I’ll eat something and then I’m throwing it back up again! Sometimes I can eat and I’ll be fine but most of the time I am bringing it back up again so I’m starving as well. It’s like a vicious cycle! I went to the Doctors and got some anti sickness tablets but they haven’t worked. I wear those travel sick bands and they don’t help with my nausea. I try eating little but often or eating fairly big meals to keep me full (which sometimes works), I’m at a loss! I don’t know what to do! Is this normal? Has anyone else experienced this? Thanks
