Drinking problem? A few beers there and then is a drinking problem? She's never drunk while she needs to work, she doesn't seem to be drunk all the time at when she's free either. She likes drinking beer but it doesn't have a negative impact on her life, does that mean she has a drinking problem? If it does you can count me in as a person with a drinking problem then. I quess I should find a clinic to start treatment or something...
As to what comes to the kiss, I think you don't really understand Misato. She's a woman who has extreme diligence in her work. Her job involves guarding Shinji and manipulating him into doing what NERV needs. Shinji's crush on her is an excellent tool in her job, even as she cares about him she doesn't hesitate to use it to her own advantage if her work so requires. That's partly why I find her so admirable. She is a regular person, even a little goofy, on her free time but when she works she ditches everything from her "other life" aside. She's cold and calculating while commanding the battles, she's even willing to
if it's what needs to be done. Seduction isn't outside her work morals.
