How to avoid lethargy while bulking?

[forsakenpowerbuilder]

I've noticed while bulking Im sluggish and extremely unmotivated. I'm not sleepy and I know I have the strength to do what Im doing; its just as if my endurance has dissappeared (and I dont do much endurance as it is).

I dont have my macros down perfectly. But i know im getting about 2-300g of protein a day and well over that in carbs and trying to keep fats to a minimum except fer taking anchovy oil in the morning.

My diet consists of eggs, brown rice, oatmeal, protien powder, powder PB, brussel sprouts, salmon, chicken, turkey, hamburger, steak, potatoes, asparagus, beets, fat free cottage cheese and fat free milk. (not in a single day)

Im 5'10 around 209lbs waking up. I know that having stimulants will help with energy but i prefer not to have any cuz I have a habit of getting up to a gram of caffeine or more a day. And syntherine gives me a heavy crash.

So any suggestions on how i might be able to up my endurance without stimulants? (NO boosters dont seem to do much when im already full of water)

Thanks

***Update: Im not sluggish from bulking after all. I didnt realize it, but its monsoon season humidity thats making me (and everyone else around me) sluggish.***
