"i started bupropion 150 once/day 2 months ago, after suffering increasing issues with anxiety and inability to think rationally. i found myself unable to cope with normal day to day issues. this medication has helped, but be careful. as many others have indicated, it&#039;s tough adjusting to it - for me it&#039;s insomnia and irrational thoughts. and even  though i &quot;feel&quot; better, my anxiety has not dissipated, just have fewer episodes. however, be aware...as i did crash hard a few weeks back, and it was worse than ever. i came through but left me little worried, as i went to a very dark place. i feel great now, so maybe it&#039;s just finally kicking in? this battle with anxiety has opened my eyes, and i&#039;m scared of what future holds for me"
