When I take certain antihistamines for my allergies, they make me feel apathetic, lethargic and a little depressed. I'm not sure why, but I've noticed that it happens with Benadryl and when I used to take Claritin or Claritin-D (can't remember which one I used to take). It doesn't happen with Zyrtec, though. If anyone else feels that way, I'd love to hear your experiences.
