I officially give up and will try to deal with the steady decline as my life swirls down the plughole. Go to bed tired, wake up exhausted, perk up slightly late afternoon, usually fall asleep mid evening then drag myself to bed. Tried and tried to find a "trigger", failed, rattle with supplements, try to maintain a decent level of exercise, but it's hard work when you feel weak and exhausted. Bloods continually show "normal, no action". Most recently had nerve conduction tests.............normal!
