Selected horoscope from www.cainer.com

Mutable signs such as Sagittarius are highly susceptible to Mercury retrograde. In your case, Mercury is associated with two of your most important houses: relationships and career. Do people come to astrology for any other reason? Not that I've heard lately. Fortunately, Mercury changes direction Friday in your most fiery, creative and impassioned chart angle. The cosmic cork pops; your energy returns to something that may far exceed normal. I also see a few karmic complications working out mysteriously well. If you dare to take a chance on something, you're very likely to win.

This maybe explains why my head has felt funny all week :O) Bloody Mercury!
