"lexapro was a miracle drug for me as far as treating my severe health anxiety and ptsd.  it gave me my life back. i can truly say i was my normal self 98% of the time. however it caused me to have extreme muscle tension and headaches. i was even diagnosed with tmj and was sleeping with a mouthguard at night. weaning off lexapro was horrific for me. it took a good 3 months for all the withdrawal symptoms to subside. thankfully the headaches and stiff jaw got better as well. i&#039;m sad i can&#039;t take lexapro anymore. it saved my life. i&#039;m about to start on prozac. we&#039;ll see what happens."
