Don't get me wrong, there are days where I absolutely love what I do. But then there are the long, stressful days with bosses breathing down my neck about ticket age and SLA violations... it gets really stressful. It doesn't help that I haven't been sleeping well lately, and that I don't take criticism well. You kind of have to roll with things like that, but it's hard for me to do.
If you are having sleeping difficulty and stress issues, I suggest something natural and green.
