I'm actually on the same regimen as you, only I don't use klaron in the morning (well I do, but I'm not suppose to
). Give it 2-3 months before you decide that it's not working. Your body needs to get used to it and adjust.
I'm actually considering accutane, only because doxy is my last option before it. Topicals only help a little for me. Unlike you I had moderate to severe acne (aka I only get cystic acne w/ the occasional whitehead). For the past 5 years my acne's been kept under control w/ amoxicillian, but it gave me really bad yeast infections. I'm just starting the doxy (second day today actually), but I'm afraid that it'll either not work or do the same thing as the amox since it's an antibiotic.
Just try to relax and give it a bit more time. Nothing's a miracle drug.
