hmm..yesh..i think waking up is a bit overrated...esp when theres no wake n bake possiblities.
perhaps there is a deeper issue that is troubling you, reinstate. i'd suggest trying to meditate, focusing on the problem for just about 10 - 15 minutes without distraction. see if you can simply resolve it in your mind. thats where the pain comes from. you may be able to peice together a solution, too.
i also think a mental "restart" suggested by mjm is good advice. thnx peas out
