Hi Ron Sanchez
Welcome to HealthcareMagic.
I would need more details to help you better.Anyways , from what you have mentioned it seems like Gastric reflux
or Hyper acidity causing excess salivation , bloating
How frequently does this happen to you ? How is your diet ?
It is also possible that you could be under stress
and so you feel light headed and anxious.
Please provide more information as a post here or feel free to mail me.
