I am one that disagrees with davejean. Being hospitalized for alcohol is not what I would consider minor. I am 52 and in my entire life I have yet to meet anyone personally that has been hospitalized for alcohol. The BAC level had to be pretty high for hospitalization.
~ To me minor hospitalization is going in with a concussion and being released a few hours later.
Plus, if I recall correctly they do ask if you have ever imbibed, so of course your answer will be yes. Now, from there at the exam the doc may ask about your drinking. You need to come clean there if they ask by stating you were hospitalized for alcohol poisoning (I am assuming it was that since you were hospitalized)
Additionally, when you go for your TS clearance this issue will come up again. Not only will it be on the questionnaire, but the people you give as references will be asked directly if you have or ever had alcohol or drug issues. If they acknowledge that as a teenager you were hospitalized and you did not than you could be in very big trouble. There are kids that have been disenrolled from ROTC for an action like that because they will go back and pull your original DoDMERB exam. To them they will than say you falsified (lied) on your questionaire. I am not sure what happens to an SA cadet, but just saying there are several here that said no to smoking on their DoDMERB, knowing they smoked 1 or 2x in HS, fearful that if they said yes, than they would get DQd. Well 3 years later when they went up for their TS and answered yes this time and gave the dates, it created the ball rolling.
