Lactose intolerance

Like a lot of people, I'm lactose intolerant.  I don't think my condition is extreme - I can drink milk, but it definitely affects how I eat.  Take, for example, my love of ice cream and milk shakes.  One thing that I've noticed is that if I eat something with my milk - e.g. cereal - I will be ok.  If I drink it straight up on an empty stomach, I'm doomed.

The Royale at Steak n Shake

Same for ice cream and milk shakes.  If I have ice cream right after a meal, I'm fine.  Ice cream as an afternoon snack, and I'm in pain a few hours later.  Milk shakes are trickier; even if I have them with a meal - the classic burger and shake combo - I will usually pay the milk tax afterwards.  Maybe the way the milk is shaken in a milk shake?  The combination of all that goodness being simply too good, and thus it has to be bad for you to balance it out?  I don't know, but it has changed the way I enjoy my burgers.  Which is specially sad, since, after moving to Florida, I discovered the greatness that is Steak n Shake.  They seem to be this local chain of hamburgers a la Johnny Rockets from California, where they have this old-fashioned look to it (but looking at vintage photos, they are probably a lot more authentic that Johnny Rockets, which was founded in the mid-80s).
