I know what you mean, Simela - when I was infected and untreated - and pregnant, I had such vivid, horrid nightmares, it got to where I wasn't sleeping at all. Any time I closed my eyes, the nightmare picked back up where it left off!! Horribly disturbing images of car crashes and other things, and always with children involved!!
So valerian use didn't do that to me, so I was good with it!
But if you know that it's the Biaxin, why not change to a different abx?
