Hi I have been suffering from anxiety and depression after an operation to remove a cyst. Everything went well but I was left with terrible anxiety & panic attacks. Was given Lustral at first but it didn't help. I am now on Effexor, just for the last 3 days. Was wondering how long it has taken to work with any of you who have experience of it? Really hoping this helps me. Finding the mornings are the worst -waking up early and overcome with terrible anxiety. Not about anything, just awful useless fear. Need some encouragement.
