Personally I would not book if you no energy for the girl your wasting your money. I would be well rested before punting. If you have a massive week every week that really has to be good money for the work. Or its not worth it. Something less demanding work wise would be better. Its probably not healthy feeling fucked up at the end of every week. Possibly your not getting a good nights sleep every night. This is dangerous for your health and will catch up with you later. Health wise.
