To answer your questions:
1) Coughing, stomach tingling/constriction/discomfort, alcohol, aspirin can all exacerbate GERD.
2) Lipitor - can cause dyspepsia (of which GERD is a possible cause) in 1 to 3% of cases.
Altace - does not cause GERD to my knowledge.
Toprol - can cause stomach discomfort in 1 to 10% of cases.
3) I am not aware of studies testing how GERD affects the absorption rate of alcohol.
Followup with your personal physician is essential.
