I am a fan of cephalosporins (Ceftin was GREAT for me), I was switched from doxy to ceftin and it was much better AND I could go in the sun. Have you tried mineral supplements like magnesium (most are deficient)? These could help with the twitching. Ah, the heavy legs, I remember those days.
Be sure to be detoxing (lots of water, lemon, dry skin brushing, sauna if you can!) Hang in there Ms. BrookieGirl.
