I was prescribed 100mg of Seroquel XL (quetiapine) each night for symptoms of Borderline Personality Disorder like mood swings, anxiety and depression. I've only been taking them for 3 nights, they knock me right out and I sleep very well, at least 8 hours. But last night the tablets did not make me drowsy one bit which I thought was very odd as the side effect should last a week and my body can't possibly be used to them after 3 doses as they are very strong. I stayed up until 4am and slept for 6 hours, I woke up feeling refreshed and ready for the day. I have felt really lifted and confident and generally good all day after being depressed and having rapid mood swings for the last 2 months. I just feel absolutely amazing, like too amazing. Life feels great but at the same time I am getting angry and my mind keeps racing and I feel like I have to constantly be doing something, feeling really irritable. I feel like its an oncoming hypomanic episode but I'm not sure. Can Seroquel XL induce a hypomanic or manic episode? I shouldn't feel this amazing and irritable :S Thanks
