Morning sickness

Anyone have suggestions for morning sickness other than mint, lemon, preggie pops, ginger, psi band, sea band, and protein? I'm almost 16wks pregnant and my morning sickness is getting worse. I'm not even able to hold down apple slices -.- also I'm having the feeling of stomach acid stuck in my throat and chest any clue as to what that could be? Calling my dr in the morning but just curious. Never had this with my son.
