@sheffieldsmith fortunately I am not having dizziness, nausea or brain zaps, I'm having increased anxiety or depression, I'm not sure what to call it, and I have pretty consistent chills. At times my muscles are extremely uncomfortable. And i dont want or cant carry on conversation . Just weird feeling. I'm not drinking any caffeine at all and have no appetite for sugar.

Look up effexor/adderall drug interactions and serotonin syndrome. Everything that's listed there. Tremors is one thing. This is about a friend of mine he doesn't drink alot of caffiene.
