On 50mg sertraline, not the first time. I was having terrible physical symptoms prior to starting which have now stopped almost entirely. My doctor asked about increasing dose. How on earth do you know? I have no idea what normal feels like as I've lived with anxiety all my life. I'm also autistic so it's probably par for the course? I wouldn't say I'm not anxious.. could I feel better? I don't know? How did you know whether to increase?
