How long have you been taking the Seroquel? I’ve never been on 25mg. I was on it for 10yrs mainly between 800-1200mg but I started at 200. I was tired the next day at the start and after dose increases but after a while that goes away for a lot of people who take it regularly. I was fine if I got at least 8hrs sleep. Problem was at the dose I was on I could (and often did) sleep for 12-15hrs. Anyway what I’m trying to say is maybe (hopefully) your body will get used to it after a while of regular use and you won’t be tired during the day?
