Perhaps you have only heard of extreme cases, in fact there could of been other factors involved, proper DX for the proper med could of been a case, illegal drugs being mixed with the use of the Effexor, doctor that is not qualified to prescribe the Effexor, etc. so many things that can a negative review of this med and others in it's category, like SSRI's, that are commonly used today, some have been getting mixed reviews, I think people have to always keep in mind that some meds are golden to some and for other can wreak havoc, at the same time it isn't always wise to mistrust meds that can be of great value towards remission, just because of a few things negative you have heard, also you need to check the validity of your source of information.
Bottom line, there are many of meds that can be of great value, if a pdoc/doc knows what they are doing, pdocs are best for mental health evaluations and such, and are specialists on prescribing the proper dosage, titration, and helping the patient find which is the best combo.
Effexor does not work over nite, like many meds today, it will take about 2 to 4 weeks to notice any positive change, decrease in depression, so do not be discouraged till you give some time to be at the therapeutic level.
I wish you lots of luck with this.

PS Several years ago I too, also had been on Effexor, I did not go "crazy" while on it.
The only problem was that a GP prescribed it for my depression, and in actuality I really needed a proper DX and med, which later I was given by a pdoc, who in which I worked with her and had come up with the right med for me and my problem/disorder.
Just my 2 cents

Take care,
