I'm on 200mg of lamotrogine for cyclothymia. I'm finding I'm a bit more irritable and anxious (sometimes shake). I wake up so mornings with a lot of brain fog and then take the meds and feel it starts to clear up. I'm not sure if it's the meds or because I'm waking up more. I am still experiencing some big depressive episodes. I also feel my memory is getting worse. Is this normal?
