my opinion . . . and it won’t be popular
You could be over-training.
Or coffee and food right when you get work might help but it seems
counterproductive to me. Food makes me sleepy (carb coma) and
coffee cancels it out so you are back where you started except
you are well fed but still tired.
I say . . .
Stop working out for a month (minimum). Whatever you lose in month or
so was not worth having / worth the effort in the first place. And don’t be
surprised if you gain size (muscle) during your time off

have happened.
If you still feel tired, that is to say the same, then it is not the weight
training. Could be all the supplements you are taking. Quit them too
to eliminate that variable then see how you feel.
When you start back training, be conservative with the weights, your
frequency and your supplements. Add things slowly so you understand
the cause and effect relationship of all. Be patient. And keep accurate
records.
You should look and feel like Superman based on what you are ‘taking’
and if you don’t, clearly a change is in order. And if you feel as bad,
that is to say exhausted, as you say you are feeling, than something
else is going on. Get a complete blood workup.
All the above can’t hurt you, and might help you. But hey, what do I know?
I wish you all the best,
