One of my biggest problems before I started eating healthier was with juice and energy drinks. I would drink 2-3 cups of juice a day, whether it was Minute Maid Lemonade, Mixed Berry, or Cranberry juice and I would also have half of a Monster energy drink each day in order to make it through the workday, since I was working at a computer all day. Once lunch time hit, sitting in one spot and staring at a screen would have me drained.
Thanks to a tip from Shawn Stevenson, I started taking a 10 minute walk outside at lunch rather than having an energy drink. And 9 times out of 10, it worked!
Another thing that really worked was fasting, which I thought was interesting... If I skipped lunch, I wouldn't feel the same crash that I'd normally have after lunch. Once I hit around 16 hours in a fast, I would actually feel my energy levels rise (possibly because my brain/body were irking me for substance).
For the juice, the only thing that really worked was making sure I had enough water each day (100-120oz seems to be what most of the experts I research state is most beneficial). This is actually an easy task to do each day if you have a bottle of water within your reach for most of the day. Besides that, the only other thing that helped was simply making the decision to cut sugars out of my diet as much as possible. Juice was really the toughest thing for me to give up.
I went 6 months with literally only drinking water and possibly 1-2 beers/week and now (as of recently), I actually started making my own lemonade and iced tea with stevia packets, lemons, and unsweetened iced tea. Stevia is a 0-calorie sugar substitute that is said by nutrition experts to be a healthy substitute but I can tell you it makes lemonade and iced tea taste just as good! Even this, I will limit myself to no more than 1 cup/day.
