Thanks guys. Yeah I wasn't looking for a cause or a long term treatment, just something to get me through these few days with work etc.
I'm not having anymore caffeine seeing as it's not helping, unless it's the small amounts in tea. Not until after I've seen the doc anyway. I was just seeing if anyone had any ideas other than caffeine that might help
I'll try what was suggested, thank-you
guess this can be closed now. Thanks
