I'm lactose intolerant, diagnosed as a young child so I just grew up drinking Lactaid milk or taking Lactaid pills. I don't do that anymore though, I'm not sure it's I've become less sensitive or just learned my limits with age and self regulate my diet. My only real concessions are not drinking straight milk or whipped cream and not over doing it with ice cream.
My only real symptom was cramping and on rare occasions I'll get a slight stomach ache probably from too much milk. I can cook with regular milk, eat cheese, ice cream, etc with no real issue.
