My moms age is 50 right now weighing 65 plus not exactly. Whenever she getting into sleep suddenly getting giddiness and vomiting sensation often. This is being happening in the middle of her sleep and early morning. She is also struggling to get deep sleep. She consulted doctors and we checked with her bp and sugar and colostral all is in proper condition but still the problem persists. No one can give a exact remedy nor finding a root cause of the problem. Dear honourable doctors, could you please some one give me the reason and remedy for my mother's problem.
