Too much sun again!

So, we have been out in the sun a couple of times in the past few days, and I find that I'm extremely sun sensitive. I get a rash from the sun going through my clothes! Sure, the summer sun here is very intense, but this didn't happen last summer. My low blood pressure may be a part of it, or it could be some of the supplements I've been taking. I have got to read up on them! This is ridiculous. I have been having a hard time with the sun for several years now (I recall feeling really woozy after riding on the back of a friend's motorcycle for the Dykes On Bikes contingent of the San Francisco Gay Lesbian Transgender Pride Parade over ten years ago), but this year it's the worst. I don't like having to stay inside all day! Ack!
