if my experience has taught me anything its that americans today dont know what it feels like to be normal. this is especially true of females. not only do adjustments take place but those adjustments create an altogether new experience.
take your time. be strong and do what you know to do. lord knows theres enough we dont know, it behooves us to concentrate on what we do know, particularly the caffeine in your case.
congrats on your progress thus far. youre making REAL progress now, the end being nothing like that which has come before. that is really good news.
