it is great to see 5 clients each day, but i really think is toooo much long term! it is a big stress for your body and for your CNS brain!
then it is up to you! it is overworking it! (personally)
meditation could help but to me you are asking too much to your self!
it is like to working out 5 times in a day, not really healthy.
Sex is like workout, you consume energy, you need fuel!
good nutrition like an atlhete, and good sleep, no drugs and alcol....
more the weather, winter coming...you feel more tired due to the change of season as well!
healthy diet, good sleep, time for your self.
