I tried taking Valerian root for anxiety yesterday evening. I took 225 mg twice. The last dose was at 9 PM. I also took my usual sleeping meds which is 50 mg of Trazodone. I don't think I slept more than 2.5 hours. And I had been sleeping good for a week or so now. The only thing I did different was take Valerian root. Is this stuff know to cause insomnia? I needed to get sleep last night. I was supposed to have a busy day. Scratch that idea.
