"started taking effexor in october and it&#039;s completely changed my life. i no longer have unusual anxiety and haven&#039;t had a single panic attack (despite being exposed to many triggers). i can&#039;t believe what a huge difference it&#039;s made. i feel like i have my life back again. i was previously on lexapro, which i found didn&#039;t really alleviate my systems to the same degree, and caused me to be tired all the time. the only side effect i&#039;ve had with effexor has been weight loss."
