I am takiing Sertraline tomorrow for the 2nd time. Tried it few weeks ago only 1/2 of a 50mg tablet. Felt really shaky, anxious and sick. I'm off for a week so have decided to give it another go so I don't have to face work at the same time. I was just wondering what other's experience of those common symptoms you feel last? I was hoping it may be a few days. Am dreading those feelings again.
