"i have been on 10mg it for 8 weeks and it works well for me. i did not want to go up to 20mg but i was going through some ups and downs so my dr. recommended i go up to 20mg.  this is my 4 day on it and seems to be working better. i did not have any sexual side effects or notifiable weight gain but i do seem to have some tingling sensation in my head.  this is my first time on antidepressants."
