I am stoping my celexa after 4 doses of 10 MG it is very hard to get a erection before celexa I could go 2 rounds at once and that is scaring me and making my anxiety 100x worse I fear my junk will never be able to work again :( I wake up if the morning the past 2 days and it was numb how long until this gets better and will I have withdraws from 4 days of use ?
