I looked Effexor up on wikipedia and it claims:
"Venlafaxine hydrochloride is in the phenethylamine class of modern chemicals, which includes amphetamine, methylendioxymethamphetamine (MDMA), and methamphetamine"
Perhaps this is why it's affecting me like this?
Ahhh yes my friend! That is why I used to love Effexor XR so much.
OK, I hope others read this because it is a little known fact about Effexor XR and they need to know. This is not my info, but was given to me by a very respected Psychopharmocologist. (Trust me these people know their Psychiatric meds)
Effexor XR (Venlafaxine) does NOT act as a Norephinepherine Reuptake Inhibitor under the 150Mg dosage. At 150Mgs and below in 85% of people Effexor XR acts only as a Serotonin Reuptake Inhibitor.
This my friend is why so many people on Effexor XR take it at dosages between 150 up to as high as 450. (Yes I said it, but you can go as high as 450 on Effexor) Beyond the 450 dosage most Psychiatrist don't feel good about it's safety. Few people go to 450, but some do and can.
So what your experiencing is probably the kick in of the Norephinepherine effect because your dosage is above 150Mgs a day. Some don't like it and other former Effexor people like me loved it at 300 because I have depression which makes you Slow and sleepy. The strong Norepinepherine effect at 300Mgs a day gave me energy and alertness that combated the heavy feeling of my depression.
Sure wish it still worked for me. I got 4 damn good years from Effexor XR before it slowly took a **** on me. Great drug and this would probably explain why Effexor is in the top 3 selling antidepressants in the world. Annual sales of 1.8 billion dollars a year! What a cash cow. Now Phizer owns it, but thats ok for them because generic Effexor sucks. (Used to be Weith until the giant Phizer bought them out.)
I guess Weith just said the hell with it because the patent is up so lets sell now why were high on the hog. Weith is no more they have been absorbed and assimilated by the giant borg.
