Congrats on the weight gain and the relatively good appointment.
I presently believe in the accuracy of throat cultures because our past three have been clear. <img src="i/expressions/face-icon-small-smile.gif" border="0"> (That's a joke, people!!).
Seriously, I take the clear cultures with a grain of salt and just smile that it hopefully means that TOBI and his friends are working. You hang in there and keep up the good work! Worrying is just a part of it all, isn't it!
