Exhaustion and brain fog

My first post here, not sure this is the correct forum...My symptoms include extreme fatigue (able to sleep any time), forgetfullness, brain fog, feelings of unreality, in addition to occasional restlessness and tingling in my feet. All blood tests are normal (incl. all the usual suspects, thyroid etc), no inflamation, heart/EKG/stress tests normal, testosterone within range. I'm a 62 year old male, professional musician. Drugs include mild diuretic (for cochlear Meniere's), Crestor for atherosclerosis and (previously) high LDL. 10 mg Prozac as the symptoms were deemed to be psychogenic in nature and as I have indeed suffered from many depression and anxiety symptoms in the past. 

Looking forward to your input

Recognizable symptoms to me, Stanislavski.  Could very well be your adrenals - forgetfullness, brain fog, feelings of unreality.  I would even include your 'Meniere'.  How is your driving the car?

 

Driving is fine (other than the extreme tiredness, yawning etc) My Meniere's is cochlear in the main - affecting my hearing more than my balance (knock on wood)

Bumpy roads would make matters worse.  When at the destination I could for a while not focus my eyes well enough to read.  

Also - While driving I somehow missed a few seconds of alertness.  Weirdest thing.  As if I wasn't fully present.
