"i took effexor for three years due to depression. i loved the fact that i was no longer depressed but i was tired all the time. i could sleep for 10 hours get up and two hours later i was ready to sleep again. if i missed taking a dose i would get a horrible headache. the only reason i stopped taking effexor was due to being tired all the time. getting off of the medication was awful. i have never been so sick in my life. if you are going to take this medicine the rest of your life i highly recommend it. it did wonders for my depression."
