Try and get more sleep at night!  Try not to eat too close to going to bed.  Try and keep all computers turned off that might be in your bedroom, including your cell phone. Also, alcohol does cause sleeping issues.  Maybe cut down the amount you are drinking, and drink more water throughout the day.

Using a good probiotic is always a good start.  Taking a multi-vitamin with breakfast is always suggested.  Good energy boosters:  Chromium; ENADA; Vitamin C.

Get out a walk 45-60 minutes each day.  That will make your body feel much more energetic.  Stay away from Sugar!
