I have been on these meds 10 years +. I am self administering far above the maximum  therapeutic levels. I have become resistant to the Meds. I am at the end of the road as to what else to do. I have delayed sleep syndrome / add / depression / dyslexia ; so I sleep for 24-58 hours, and i am awake (?) 10-28 hours per cycle, meaning... Semi functional 2 nights and 3 days (IF this or less a week). 
Every year it gets worse... I am So tired. Any ideas? Thank you . J/C 
I used to swim and walk, that was helpful, but in the last few years, I lost the energy and desire for it. I feel like i am a lost cause now.
