Get rid of the pimples please!

ARGH. I am having pimple problems again. I blame the weather and stress at work. First off, the weather can't decide if it wants to be warm or cold or rainy or what. It's wreaking havoc with my body. Second, this is a rather stressful time of year at work. Of course, it makes my entire face break out. Does anyone have any good suggestions for acne treatments? I have combination skin and I am willing to try anything. Suggest away!
