I feel great hitting the gym about 15 minutes after I slam 1000 cals of shake (make the night before) and toast with nutella. I don't really sweat it if I can't finish my shake and only get in 500 cals some mornings. But 8g carbs? Why?
That's not to say the "faintness" you're feeling is definitely to do with your meager breakfast. I think most folks experience darkening vision, shortness of breath, or partial hearing loss at 300-something squats on the LP. I find I have more of that when sleep and other stress is the issue, not food.
