How do I boost my Energy Levels and keep concentration?

I have two problems here lack of and/or diminishing energy as the day progresses and dips in concentration. Most days, I will go for a run (2-5 miles a day), practise 1/2 - 1hr on the piano and go to work (part time). I have just started attending college (part time, three times a week) and I am concerned that I will not be able to sustain my concentration and energy levels. I usually drink one can of red bull a day (just before work), like I said I do exercise and play the piano, which I find both relaxing and I go to bed early. The problem is if I go to bed around 10-11pm I will wake up around 2-3.00 am and then will get back to sleep around 4am. I feel ok in the morning but as the day drags on my energy and concentration saps. I already take Sanotogen Gold A-Z multivitamins as well as Evening Primrose Oil and Ginkgo Biloba - I cannot take Ginseng as I suffer from bad headaches and migraines.

Any top tips to keep my energy and concentration levels up throughout the day, please

Reply:Honey red bull equals to 5 cups of coffee with the same proportion of sugar, what sugar does, it's that it boosts you for a couple of hours and the you crash, so watch what you eat, a healthy diet can do wonders on you; if you still need extra boost, there's these little red bottles thats say 5 vitamines whatever, it helps a lot without the crashing; you can get them in GNC or at gas stations, it will help you.
Reply:Sounds like you are vitamin B deficient. There is a company called Market America. They market 2 products one is called Isotonix B- Complex which will give you energy and possibly eliminate your head aches. The second product by the same company is called Macho Tonix this is an all natural supplement that will give you a 6 to 8 hour energy boost and enhance your mental clarity and not give you the crash effects of red bull. hope this helps.
Reply:You could try switching around the foods that you eat. Make sure you get a larger high energy meal for breakfast and then something lighter at night. It might help you sleep better at night too. Also instead of red bull, tea or coffee before work, you should try fruit juices. Eeeer making sure you are fully relaxed before going to bed might help too (e.g. yoga or just giving yourself 10 minutes without tv/reading). I'm not an expert but i've tried so many things myself.
Reply:Besides an energy multivitamin every day you could also take chlorophyll, barley grass or wheat grass.
