Is anyone else having exhaustion issues?

I will put my hand up for exhaustion - sometimes I come home at lunchtime and sleep for 30mins and then go back to work - I am lucky that I work 10mins from the house - this is the only way I can get through the day, my GP said it is the meds that are making me feel like this.
Good luck with the Pain Management, I felt this was the department that really understood me, the neurologist was useless.
