So I've been reading these boards for awhile...just now decided to register and be a part of it! My surgery date is THIS Friday....I'm freaking out a little bit! I've had SO many questions answered on here, but one thing I'm unsure of as I've read conflicting things....is caffeine a yes or a no after surgery? Just wondering if I need to prepare myself for no morning coffee anymore! Any other advice or quick tips would be appreciated....LOVE these boards!!
