i can tell a difference between the MRSA and Psuedo. When the MRSA is acting up, i feel really fatigued and cough up green gunk. i just don't feel as bad when it's the psuedo though. anyways, i always get sick when i first start my tobi, but this time it's worse. i think my allergies may be causing problems too. i've had like 10 sneezing attacks today, my eyes are watering, and my ears feel like they are stopped up. i'm also wheezing, which is something i haven't done since i was about 10.
