Being tired throughout a day is not normal even your workouts are intense. I had a very similar issue, I was feeling very tired after my workouts. Later on, I figured out that I have high blood pressure problem. Please go to a doctor and get checked your body up, especially your heart. Drinking energy drinks is not the real solution and may worsen the situation since they may effect your recovery. Besides, lifting very heavy every day is not optimal and may burn your central norvous system out. If there is no problem related to your health try these 1. Change workout system. 2 or 3 times a week, concurrent style gives very optimal results. 2. If you are on deficit eat more. 3. Sleep enough. 4. Drink enough water, eat vegetables and take vitamin tablets. Please keep me updated.
