"i&#039;m on the generic version citolopram. first 10mg for 7 days then up&#039;d to 20mg. now on that for little over 4 weeks. still feel blah. i&#039;ve been switching when i take it to see if it helps sleep. well apparently you need to take at night! it&#039;s cousin to lexapro. i just took my 20mg at 9a.m.(to see) an its 2 hrs later an i&#039;m very sleepy. i&#039;m giving it 6 wks . i&#039;m on med #7. i hope this works. not many left for me to try. not much side effects with celexa. occasional anxiety but i also have klonapine when needed. so going back to take at night. i am having night sweats occasionally  also but lethargy during day."
