I disagree with part of that also Rose, based on personal experience. I take an anti-depressant and an anxiolytic. I don't recall the anti-depressant I took before Prozac but it was an old school drug. Elavil or something like. The difference was night and day.
When I was switched to Effexor XR I didn't notice a difference. A couple of years or so ago I wanted off of Effexor. I tapered slowly and used Prozac to help with withdrawal. The Prozac definitely helped with that but I immediately crashed into an awful depression. We upped the dosage and there was no change. I chose to go back to Effexor and the depression improved.
I've been prescribed three anxiolytics. Xanax did absolutely nothing. An M&M would have had more effect on me. I've known people who used Xanax as a recreational drug so it must make them feel pretty good. Ativan worked... sort of. It was too sedating and the anxiolytic effect was too short lived. Clonazepam was perfect. I didn't feel sedated. I just felt a great deal less anxiety.
On the original topic I still have the same opinion. I may be skeptical of 5 to 7 drug cocktails but it isn't my business what other people take.
