Gosh I do admire your determination. For sure if you are influenced by Buddhist philosophy greed is one aspect to suffering. I found this assertion I could easily accept as you don't have to go far in my home country to see this suffering from greed. If you are also of the opinion that there is no such thing as an 'I', which is actually just a social and cultural construction, you will also know that hunger is also a social and cultural construction and that a real hunger is nothing at all like a habit for eating which is often masqueraded as hunger.
