Hi Doctor,Thanks for time. For the past few weeks I am having a bad stomach ache. When the stomach ache starts I feel that my body is generating excess saliva, which is moreover watery. In this time, I feel so tried and feel little bit drowsy. This last for 1 to 2 hr and vanishes, but after some time this repeats.Am bit afraid of this. Please suggest a good remedy. Note: Am a Male of 27 years old.Social drinker / smoker.In the past week, I do had some liquor and N/V s.Many Thanks,Krishna
