Can you get immune to coffee

Question

some people drink coffee everyday to start their day off so it must give them a jolt still, but can they get immune to it and not get that caffeine high anymore?

Answer 1

yes you can become tolerant to it and it wont be as effective

Answer 2

Yes one can build a tolerance to the caffeine  

Answer 3

You'd have to drink a ton of coffee to become immune to it.  I suppose you could if you drink too much but expect some nasty side effects if your a heavy coffee drinker and then stop.  

Answer 4

Regular coffee drinkers don't become immune.  Their bodies still get a kick from the caffeine.  If they did not drink the coffee, they would develop withdrawal symptoms such as tremors and headaches.
