Oh, wonderful. For the last week or so, I have been constantly tired, fighting off sleep at every turn. I assumed it was exam-period stress or something of the sort. I think I was wrong. I think it has something to do with my lexapro; specifically to do with the doubled dose I have been taking. It was meant to go back down to 10mg in March, but I haven't tapered off yet. I think that I need to break my remaining 20mg pills in half and hope that helps. If it doesn't, back to the nice lady in the white coat who gives me my prescription.
