This past week I have been completely down and out of it. I was extremely sleepy and practically in a daze at times. In fact, as I type this I just want to lay down my head and nap. Well it seems as the prescription Zyrtec I'm taking is rearing it's ugly side effect head and causing drowsiness. This may not seem odd because of the fact that it is an allergy medicine, and is an antihistamine which is notorious for causing drowsiness, but I have been taking Zyrtec every allergy season for the past four years now. I cannot ever recall feeling this way or sleepy unless I just always uncorrelated the two. Zyrtec works great for putting away the allergy symptoms. It also worked a lot better than the over-the-counter Claritin stuff. So for now I'll try taking it just before bed instead of in the morning to see how that works out.
