1 tin a day.. it varies from time to time.
You are a grown ass man, if you want a dip then take one. I go through, on average, a can a day. It depends on what I am doing, and how I am feeling. If my boss is being a dickhead then I go through more. It all just depends, dip how much you want man.
Usually a can lasts me about 2 days, sometimes more sometimes less.
