I for one enjoy my coffee too much to give it up!
We have, however, changed to the "lite" half caf stuff, which I enjoy just as much... eventually I iwll hit the total de-caf, but for now this works for us!
I enjoy my tea in the evening before bed... it "soothes" and "calms" me - so not sure I'd want it for my workday "boost"!
Congratulations on getting into your wedding dress "quicker"... just remember quick weight loss isn't always the healthiest way to go! Good luck losing and keeping it off...
