I have been on intermittent Lupron for over ten years after biological reoccurrence after robotic prostatectomy. Fortunately it has worked well to keep my psa in check but fatigue and general loss of stamina has kept me from engaging in many physical activities I used to enjoy.
FORTUNATELY I have been prescribed Nuvigil, a stimulant that has put the “energy” to enjoy life once again, not simply mope along. Although it acts as a stimulant via promoting wakefulness it is not a central nervous stimulant like Adderall or old school Dexedrine and other amphetamines, so it is not a highly controlled substance.
This is a medication you actually feel when it kicks in and frankly can create mild euphoric effects as well. Has made a significant difference in my qol. Highly recommend
