Stress Center Peer Support

This spring I kept feeling tired in meetings and such. Didn't want to go downt he cafiene path so I started doing research. Many said that CoQ10 is great for increased energy. Took some and it did help. Later I took a little higher dose. Energy picked way up. However, I started feeling like I was going to jump out of my skin, was irritable, and had trouble sleeping. I didn't make the connection to the CoQ10 causing this and started to really go nuts trying to figure out why I was feeling so anxious and my coping skills weren't helping. Bad place to go. Anyway, I quit taking it and am feeling better but still having some anxiety, but getting less every day.

Has anyone else had anxiety caused by a stimulant or something similar.
