I work different shifts which can be good and bad. One day I was suppose to work between 2pm-11pm. I ate my lunch and then went to take my multivitamin. I often take benadryl to help me sleep but out of habit I took a benadryl by mistake. I realized this as soon as it was too late. It takes about an hour to kick in, which was the time I was suppose to be at work. So I tried to eat more, drink soda with caffeine, and some water. I was hoping all this might dilute the effect. I certainly didn't want to be asleep at work.
So I get there and I can start to feel it. I tried to stay alert to keep my senses sharp. But after awhile it could not be helped. I was drowsy for sure, and there wasn't much else I could do. I never fell asleep, but I felt like a slow-moving turtle. And no anger at all, which I don't tend to get angry at work but there are those annoyances. This feeling only lasted a few hours which was good. A little while after I got back to work after lunch, I was back to my old self.
