You should talk to your doctor about this.

I recently saw a Tom Scott video about how 'stale air' can have a lot of carbon dioxide in it, and you can lose like 50% brain cognition because of it. Makes you feel nauseated, sleepy and can give headaches. You should probably just see your doctor, but that might be something to keep in mind.

Go on a walk.

Also, aminos > coffee.

I walked to the comic shop and back yesterday in the shit ass snow. also you're at work, get off the furry prons

I know the feeeeel.

switch to something a little more potent than coffee, like cocaine maybe?

You may want to try adding Vitamin D and tryptophan supplements to your diet, a lack of those can cause this especially around this time of the year. If you try it, it will take a week or two to start working.

Agreed with the Vitamin D bit. My doc calls it the "feel good vitamin".

If you take Vitamin D supplements, make sure it's Vitamin D3. It's the closest form to what your body naturally produces from sunlight (D2 is made from plant sources), raises the levels more and keeps them up longer.

Precisely. Now consider that L-Tryptophan is required to naturally synthesize serotonin

Eat apples. It has a protein that's more powerful than caffeine.

Apples have no relevant protein. Whole fruits do however have a great deal of health benefits that can make you feel more energetic and healthy.

Coffee won't help much, it's only temporary. Good nutrition, sleep, and exercise help the most. Since you're already getting enough sleep, just be sure to have as many fruits and vegetables as you can, and don't skimp on meat. Exercise will make you more tired at first, but will also help you to sleep better, and have more energy in the long term.

Might also be Seasonal Affective Disorder. Treatment is easy, need an hour or so of full spectrum light daily. (summer sunlight equivelent) With the inexpensive LED lights now, these full specturm lights are not that expensive anymore.

It could be your thyroid mine went out this time last year.

If caffeine isn't working, try eating a banana. I used to have to work late night (sometimes even until the next day) at my old job and experimented with a lot of energy drinks; the caffeine boosters didn't work for beans, but I did get the desired effect from the ones with letter-vitamins and potassium.

Also, if you're getting your caffeine from soda, watch the sugar content. Sugar is a false high -- you'll feel energized (or, in my case, just cranky) for ten minutes, then crash. And whatever your preferred method of caffeinating may be, work on it slowly throughout the day. You can substitute a Red Bull for coffee, but only if you drink it like coffee, IE: sip it periodically throughout the day instead of "pounding down" one because they're so hideous.

Do you have sleep apnea? I know my roommate has big problems with that affecting his daytime energy levels...
