Dealing with a (gag) yeast infection?

Okay, so I began treating the infection on Sunday night. I fell asleep last night without taking the third treatment so I took it this morning. It felt like everything was going well until I took that third treatment. So my question is, did I screw up the healing process by skipping a treatment? Also, will taking a treatment during the day irritate me more than it would if I were laying down not moving to go to bed at night? And how long can one of these wretched things last? Today is day 4 with some sort of treatment being used. I'm beginning to worry, I just want it to go away!
