Being Sick SUX!!!!

I have gone 2 years without being sick and since the beginning of 2010 i have been sick 3 times!!!!!! I feel like my immune system is not working!!!! I have been going out way too much. Im sure thats contributing to it, and also im drinking alot more than i used to (socially). I think its time to get back in the gym, start taking better care of myself.. minimum drinking, better diet. Lets see how long that lasts lol..
