So I took my first dose today, 25mg of Sertraline. A week from today I start taking 2 tablets (50mg) and in 2 weeks I have a follow up with my doctor.

I took my first dose around 10am. At around 1130am I had a very odd 5 minutes were I just kinda sat in bed and felt like the room was gonna explode or something, just very fear stricken. I figure there is no way it's already the Sertraline as it is day 1 with it.

I'm assuming I'm just overreacting as I feel much better about it now but I still feel slightly on edge. Is this normal?
