Re: excessively sleepy
Get your iron/B12 levels checked...do you eat a good diet?
there are many things that can cause this sleepiness and the first one that springs to mind is adrenal fatigue brought on by your busy/long schedules.
Get your thyroid levels checked too (Ft4, FT3, TSH, thyroid antibodies)
Things that can help adrenals are...a good vitamin B complex.
1000mg vitamin C a day
and an amino acid called L-tyrosine 500mg a day on an empty stomach.
I would aslo take a good multi vit/mineral to cover any other deficiences you may have.
