Glad you made it through and live to share the story! I stopped drinking coffee like 3 months ago (used to have about 5 Italian style a day) and yes, the first week was like a very bad hangover, plus my workmates would look at me like an alien (free coffee in the office). Thing is, after that initial backlash, it only gets better. Now most of the time I have the energy and impulse coffee would give me, but without the drawbacks. Makes me wonder how I got the habit in the first place. Enjoy!
