No, I have not been through a Zeppelin phase. I've been through plenty of phases since I discovered the joys of rock and roll, but Zeppelin remains my constant favorite (well, tied with The Doors and the Stones of course). I don't think I'll ever stop loving their music. Often when I hear a song too many times, I get sick of it, but so far this hasn't happened to any Zeppelin songs, even the admittedly overplayed Stairway to Heaven. If Zeppelin comes on the radio, the radio gets turned up, no matter what.
