Success through Addiction

I need to write about 5000 words per week to finish the first draft of Book 2 by Valentine's Day.  Just now I completed that quota for the latest seven days.  (My weeks run Saturday through Friday).  But here's the price I pay.  On the way home from work, I stop at a local cafe and write.  Etiquette requires that I buy something, and this establishment can conjure up a pot of green tea that's quite delicious.  One problem -- it's caffeinated.  After a few days of drinking anything caffeinated, I'm addicted.  What do I mean by addicted?  I mean I like it and if I don't have it, I suffer withdrawal systems.  I started writing a little later than usual yesterday, and I felt as though two invisible hands were tightening a belt around my head.  A couple of Tylenol and a glass of caffeinated chai, and I was okay.  I'd given up caffeine some years ago if for no other reason that the fasting on Yom Kippur was torturous.  Now I'm hooked again, but productive.  Is it worth the occasional headache worth it?  You bet.  Gotta suffer for your craft.
