argh

I only got two and a half hours of sleep last night. I do not know what my problem is. It is 6:30 am and I have been wide awake for an hour and half already. I took a Claritin Liberator yesterday morning. I have felt buzzy since supper time. One of the rare side effects is "unusual excitement, nervousness, restlessness, or irritability" but that is not really how I feel. I have dry mouth and I know that is from the Claritin but it has never effected my sleep before.
