"i have suffered from severe anxiety (gad) and was taking more and more klonopin as time went on.  i am very sensitive to medication and have tried many different ssri/snri&#039;s through the year with horrible side effects.  finally, i had dna testing to see what i would respond to and the result was pristiq.  i started it several months ago in a small dose (i split the pills even though they say don&#039;t do this) and within a few days my anxiety literally went away.  i was able to cut my klonopin in 1/2 over a two month period.  the first week or two i was extremely tired but that passed.  the only side effect i get from time to time is migraines.  it still amazes me that my anxiety has disappeared.  i no longer keep klonopin in my  pocket!"
