Hi saw GP a week ago and he changed my sertraline from 75mg to 100mg. Day 7 and I feel horrible still, really tired, brain won’t work. I went to ask for counselling support for trauma and walked away with this as a “solution”. Tempted to drop back down as feel like I’ve been drugged. Well guess I have. Question is does it improve? Or is this what 100 feels like? I didn’t feel the change from 50 to 75. Wondering if I need to give it longer as feel like a zombie and not functioning.
