Ahhh...I've heard this many times.
My advice, since you're not asking ;), is to start slow. Buy a bottle at a time of different types.
Don't drink them when they are "too" cold. Use a small glass. Pour into the middle of the glass until its half-full...then stop. Let the head rise...then subside a bit.
Sip first. Then drink a mouth full. Learn about the after taste...the 'mouth' of the beer.
Then try another type.
Experimenting is the fun part.
I love ice cold beer, just above freezing is the best temperature for me.
