I started taking ADs about 6 weeks ago for PND and anxiety issues. I feel like they are really helping and feel normal again. I wonder though how I will know when I will be ready to stop taking them (I know its only early days) a couple of times I have forgotten to take it in the morning, by the time I had rembered it was late evening and have found I felt down and emotional again for a day or so. Is it normal for the effects of the medication to wear off so quickly? and How will I know when the PND has passed or whether its the medication making me feel better
