I had a really hard day, so I decided I would just exercise till I collapsed. I worked out hard for two hour straight. By that time my muscles were shaking, but mentally I was able to keep going. I only stopped because my husband asked me to. 

Somehow I’m hardly even sore this morning tho. I work out semi-regularly, but never like what I pulled last night. I couldn’t even fall asleep well afterwards because I just wasn’t tired.

Has anyone else experienced something like this? Is this mania that’s somehow giving me strength beyond my normal?
