"i&#039;ve been on 10mg fluoxetine for just over one week - i did take it for a few days a little while ago, it made my ibs worse, so i stopped. my doctor persuaded me to give it another go. i know it&#039;s early days, but so far it&#039;s all bad! before i was  tired, unmotivated, no concentration, barely able to wash or do the simplest things. now - i&#039;m like  the walking dead! even more tired, even less motivation,  brain fog - you name it. and possibly more  depressed! i also had terrible joint pains - i have arthritis anyway! the joint pains seem to be lessening, the others aren&#039;t- so far!  i just hope it&#039;s a case of getting worse before it gets better, cos atm it&#039;s almost unbearable!"
