Hi Bo Snow,
This is one subject I know quite well - been on it twice in the past for generalised anxiety disorder.
It works on Noradrenaline and Seratonine receptors so really helps with anxiety. Please, please, please always take it with food otherwise you will feel nauseous.
So, like most ADs, they take their time to get into the system and start working so be patient, I know it's hard but it is worth it.
Keeping my fingers crossed for you.
