I wasn't able to get enough sleep last night.  Actually, I had difficulty sleeping this past week. I don't know why.  Good thing that I am still able to work despite of.  I was tempted to file for a leave today because I was still groggy while I was having my breakfast earlier. But I know that I couldn't. I need my vacation leaves for seminars, appointments and other 'must personally attend' wedding requirements. Buti na lang at Friday na, at least I'd have the weekend to catch up on my zzz's.
