Do i take the gi cocktail on an empty stomach?

Depends on what for: Generally "GI cocktail" is antacid/anti-gas/numbing medicines. Taken when symptoms e.g. heartburn/dyspepsia occur, often to distinguish causes but not as long-term remedy - thus when taken depends more on when sxs than necessarily timing of meals. Would require MD followup esp w Gastroenterologist if persistent to assess causes. Happy to review the details in consultation, if further question
