Does anyone else experience sudden tiredness/fatigue? I get it daily, 2-3 times a day. When it happens I could just close my eyes and sleep. I get very moody and snap at people around me. Similar to how we get moody and snappy in the "fight or flight" situations.

Funny thing is though, when it happens I work myself up, have a panic attack and it goes away. It's as if the panic attack cures it. The only other thing that will cure it is a beer.

It could happen anywhere at any time. Really does my head in!!
