Caffeine is addictive, there is absolutely no denying it, which means that you probably will suffer from withdrawals.. I have never been a fan of coffee or caffeinated products myself, but I know a few close people who have suffered from caffeine/Coffee addiction (not exactly Monster, but of the same ilk).I'm not sure how you would do this with Monster, but the person I know who had a coffee addiction problem (my mother, actually, heh.) had me confiscate her coffee and over the course of a few weeks give her ever decreasing ammounts of it.Similarly, you could try asking a friend you know for help, or find a motivation to stop drinking it. Chances are, you'd rather not feel like you're dependant on a chemical to live your life properly, and sometimes this can be enough motivation to stop. Going cold and immediately stopping however, will make you rather unfriendly and short tempered, but it should gradually improve ;)
