I also have a similar issue. I love shaving so I try to shave everyday. If I do this, I get red patches here and there plus some irritation. If the irritation is too much then i take 2-3 days off. The next couple of shaves are great and usually for 2-3 shaves I don't get irritation, but I get an occasional shave that is just bad.
I say try a day or two off...
