In general when I do squats and deadlifts I sometimes feel light headed
- are you holding your breath through the lift? Maybe this is a breathing/bracing issue that could be eased decreasing load?
and it drains my energy abit.
- Moderate/hard training should tire you out, this seems fine.
Is this a symptom of anything or is this normal?
-This would be a question better suited for your doctor, not an unmoderated internet forum
