Counting Sheep

Okay so lately i've been having some trouble sleeping and a couple night ago decided I would try an old trick that has worked for people for many years. I thought I would start to count sheep. I have found out that it is way easier to count sheep jumping over a fence than to try to count sheep one by one in a herd . Sometimes sheep in a herd move around and I lose count or count the same sheep twice, I then get so frustrated with myself that I lost count and I have to start over, by doing so I keep myself awake even longer because I'm thinking about sheep at all hours of the night.
