My Dr. gave me a sample of Xanax (I think this is the drug you called Zanix) when I was going through a divorce. He said to only take it just before going into difficult meetings with the Ex. The Dr. said he regularly prescribes it for people with a fear of flying who have booked a holiday in Timbuktu.
To make a long story short, I got through a meeting and went back to the office to carry on with some work that required high concentration and attention to detail. I couldn't believe how productive I was.
The next day I looked at the quality of work done under the influence of Xanax. I had to re-do it all.
Don't drive or operate machinery when on that stuff. You are a serious risk of hurting yourself, or somebody else.
The Dr. also said he didn't prescribe it for regular use because it was addictive. But it was effective if taken before predictable anxiety... like flying.
Finding a peer support group contributed strongly to my recovery.
Good Luck.
