after taking the starting dose of effexor xl, the first day, i experienced the worst panic of my life. my heart rate and blood pressure were sky high for like six hours. i was also having a great deal of trembling and muscle twitching, electrical sensations in my body, and i was so incredibly panicked.
i do have another medical condition which is suspected to involve my norepinephrine. however, i am wondering if anyone else experienced this??
