I feel that fatigue is a common and perfectly normal result of many things, age being the main culprit. Before seniority afforded me easier jobs, my warehouse work gave me an intense physical workout every day. I've had 3 knee replacements, 7 lower vertebrae fused and severe arthritis. In the early 90' I could work a midnight shift, get my girlfriend and drive to Myrtle Beach or even in mid-2K drive a bus all day, grab my "best" girl and have breakfast at Abby Road in Virginia Beach. Now I want a nap after going to the grocery store. I blame much of my fatigue on the 3 different drugs written by 3 different "professionals" in the same coronary practice? I'm convinced the drugs add to my fatigue since it is a listed side affect. Reminds me of the old saying, "the operation was a success but the patient died"? 😎
