Coffee is my only vice. I don't drink alcohol, no tobacco products, no gambling, no other addictions of any sort.
I started drinking coffee late in life, back in 2011 as a matter of fact, when I went back to get my college degree. Working full-time and having a boatload of homework, I needed something to get me through the day.
I drink one 16 oz. cup of coffee in the morning, and that gets me through the day, now. I was up to 32 oz. a day. I did get horrible headaches when I cut the after noon serving out.
I can't imagine giving up coffee completely, it's so delicious.
