nOt much time left in day to add more excersises. Not sure how much more I can cut back in diet.

If you aren't doing it already, try drinking water = 1 ounce per pound of body weight, as an example, if you weigh 125 pounds, drink 125 ounces of water per day.
By doing this, you body will no longer think that you are dehydrated and begin releasing water that it is holding onto. Everytime I do this, I end up dropping about 6 pounds in about a week.

A tip I read is to eat an apple before dinner (or going out) Apples are a metabolism booster & will satisfy hunger then it will attack the fat before it can be absorbed into your body.
Use smaller plates when eating, measure portions etc.
Keep in mind you may be shape-shifting building muscles but weighing the same (possibly more) but you are still losing. Toss out your scale and use a cloth measuring tape and journal your weekly progress, you may be suprised how much you are really losing.
Drink alot of water & fit in another 30 min walk, you can do it on a lunch hour or get up an extra hour in the morning. If you have a dog, take it on a long walk, this helps you keep a great pace and your dog would love the added attention. If you dont have or want a dog, ask to take your neighbor's dog out.

Not a weight loss tip, but an English tip. The word plateauing doesn't exist. Look, four vowels in a row. Reaching a plateau is the way to say it.
You don't need to add exercise, just change the exercise in your program. Get your cardio in a different way, and definitely add resistance training or circuit training to your regimen.
The frontline of weight loss is your diet. If you're not losing, change your diet.

There is such a thing as too much exercise. I have recently lost 105, and have plateaued. Try fasting for a day or 2. Just juices, that helped me.

try listening to some motivational audio books at night, before you sleep and while you are sleeping

Change what exercise you do. Do a lot of CV at the mo? Cut back, and do more resistance (weights) training. Do lots of weights? Then do more CV.
Go running for 30 minutes on treadmill? then do 30mins on cross trainer instead.
Do 10 minutes on treadmill, 10 minutes on bike, and 10 minutes on ergo (rowing) machine? Then do 30 mins on just one.
Go for more calorie intesive workouts - like on the cross trainer.
Building a bit more muscle will burn more fat. So change the resistance training you do. If you do lots of reps, small weights, then do few reps, higher weights. Few reps, heavy weights? then more reps, lighter weights.
Just chop and change your routine. Your body gets used to its exercise after a while. It needs shocking into further change.
Oh, and despite what the guy above says, do not, I repeat do not, fast. It doesn't work in the long run, and puts undue stress on your body.
