"started taking this a week ago for moderate depression and anxiety. i&#039;ve been on zoloft and paxil before but the zoloft made me exhausted and the paxil made me gain weight and missing doses caused &quot;brain zaps&quot; like mini electric bolts. i felt better the very first day, and i knew the exact moment it came on. even a coworker noticed my smile was like nothing before. every day thereafter my mood has been amazing.  my doctor told me to start with 10mg, and then 20mg after a week but i jumped right into the 20mg because i know my tolerance for medicines. i still have some social anxiety so he may bump me to 30mg next visit but right now even at this dosage i feel like life is worth living and is manageable."
