It seems like you're feeling tired in the morning despite taking Modalert, and your
TSH, hemoglobin, and
B12 levels are within normal ranges. Based on the information provided, there could be a few potential reasons:
Vitamin D deficiency: As suggested, low vitamin D levels can cause fatigue, so getting your vitamin D levels checked could help.
Other underlying conditions: Generalized weakness and sleepiness could be caused by other conditions such as sleep apnea, chronic fatigue syndrome, or certain cardiovascular or neurological issues.
Medication review: Sometimes, certain medications can cause drowsiness, and Modalert’s effectiveness may vary in some individuals.
It would be helpful to get a more detailed history and possibly further tests like vitamin D levels or a sleep study to rule out other causes.
