Alprazolam
"Xanax is a wonder drug. It's effects are felt quickly, but doesn't have a long half life. I am on 5 x 2mg's a day for Panic Disorder and Anxiety. I also take Methadone 80mg's when I wake up. I never take Xanax at the same time. I always wait at least 2 hours. I don't drink alcohol. I'm also on 400mg's of Seroquel at bedtime and 60mg's of Restoril. I have been on these medicines for about ten years. Methadone has a bad rep. If you want a fast acting anti-anxiety/panic disorder medicine, Xanax is it. If you have insomnia, Seroquel and Restoril (in the benzodiazapine family) are good as well. Hope this helps."
