"i&#039;ve taken 20mg of citalopram for a little over two years and while it has helped ease my depression and anxiety symptoms, i&#039;m not sure the benefits have outweighed the issues. my mood has improved overall and i have far fewer panic attacks than i used to, but i definitely have weeks where i feel absolutely terrible again and its effectiveness seems to have worn off over time. the biggest problem i&#039;ve had is that it&#039;s caused issues with my attention span and i my head feels foggy much of the time. my doctor suggested cutting the pills in half and that seems to be helping, but because of the haziness i am really considering a change in medication."
