A couple of questions please

[humdroid]

Y used to take valium twice a week.
He used to take anything from 5mg to 15mg in one day, ususally five.

Y read about valiums withdrawal symptoms not kicking in for three weeks.
Y got very scared and on 22/4/09 decided to stop. Y has not had any for nearly 20days, so hopes to see an end to these awful symptoms real soon, is he being over optimistic?
Y knows stops are dangerous but he hadnt had valium for a week so he stopped.
All was well until day 10 - present and Y's anxiety and depression ramped up.
Y was taking zolpidem, but had just had a weeks break. He took zolpidem from 4/5109 - 7/5/09 10mg-15mgs a night. He stopped taking zolpidem on 7/5/09 as he heard it was cross tolerant with valium, and he didnt want the anxiety to get any worse. Y remembers asking his doctor if valium and zolpidem was cross tolerant and doctor said no. Y heard in the internet somewhere, that they actually were.

more Q's pls
- can Y take valerian, or will this add to his w/d symptoms?
- are zolpidem and valium cross tolerant, and is my doctor right?

Y is having a bad time with anxiety and depression, and needs some relief. Any ideas welcome what to injest (except sunlight and excercise, cos he knows about those)

Y says thanks
