"i was prescribed effexor for anxiety which interfered with sleeping - worry about getting to sleep meant that i wouldn&#039;t sleep which made me feel exhausted, depressed and useless. i&#039;ve also tried zoloft and luvox which didn&#039;t do anything. cbt and mindfulness were also pretty useless - just made me slightly more obsessive about my weird problems with getting to sleep. 



effexor has been amazing. apart from some insomnia and lightheadedness during the first week i don&#039;t have any side effects. i don&#039;t have the same obsessive and weird anxious thoughts over getting to sleep or other minor things which preoccupied me and made me feel dreadful. i sleep well and my head feels so clear."
