Hello Welcome in H.C.M. I have gone through your query regarding dizziness and acidic taste in mouth after smelling vinegar. Regarding above I would like to tell you that nose is playing very important role in the identification of flavor of any thing taken orally. For clarification of above statement here I am telling you that whenever any sweet gets a little bit rotten at that time also it remains sweet but it s flavor changes to little bit pungent and on putting it in mouth one may say that this sweet is rotten and not be eaten. In the same way whenever any thing is being smelled, the same stimulates our taste buds of tongue and one may get the sensation of that particular taste. If the smell is quite deep it may affect the concious level as well as happens in the case of chloroform. Regards.
