Still At It..

I'm finally getting over the urges from nicotine.  I can say that my health related anxiety really drove me to quit.  I'm not sure if this made it easier for me than others. I still have episodes of PVC's from eating, sleep deprivation, dehydration, alcohol hangover, high stress situations, and anxiety.  My heart symptoms have really deprived my motivation to do alot of things I used to enjoy. They have lead me down a lifesytle path that is unproductive and unhealthy. I have struggled lately with some bad eating habits only because I've been so deprived of things that made me feel better. What on earth do we have to do to make ourselves happy again after all these addictions?  Food Overeater, Smoker, Alcohol Binge Drinker, Caffeine (Soda),.  HOW DO YOU QUIT all of these?  What can you replace them with? I can tell you quitting all of these at the same time has its benefits but it as left me very depressed and irritable. I have to quit because I fear my heart symptoms are related to my lifestyle, but I'm realizing that this may not be true.  Sheesh.  Life goes on....
