I'll never forget the day I moved up to 1/2. I lost like 10 buy ins during the first hour. I'm a nit, so I probably had 50 buy ins, though. And there was just no way I was moving down or quitting, so I played like 15 hours straight, winning most of it back. As I recall I didn't eat, go to the toilet or blink an eye during that period of time. Having said that, moving down to regain the lost confidence and $$$ is probably better for your mental and physical health.
And start raising the limpers.
