Losing rapidly is not safe. 1.5 to 2lbs a week will give you longer lasting results. If you are losing that fast it may mean that you are not taking in enough quality calories and probably starving yourself. Chances are you may be losing muscle as well. Increase your protein intake. Any idea how many grams you are getting in a day? That will help with the recovery. You can exercise hard as long as you give your body adequate fuel and rest. Slow down though until that happens.
I've overdone it a few times in the past to the point where I am so sore that I can't sleep. Not a good thing! It means your body is telling you to get some rest. If you don't you also run the risk of injury.
What time of the day do you workout and for how long? How many days a week?Whats your split look like if you are doing a split?
How much sleep are you getting? If working out hard core (6 days a week = 3-4 resistance training days + cardio on all the days) you need more then the avg (typically sleep deprived) person. Bodybuilders sleep at least 8 hrs and typically more when they train. I felt really good at 9 hours when I was lifting heavier.
What does your diet look like? Toss what you ate yesterday in

If you still can't get good sleep in after you slow down for a couple weeks and are getting really sore then you can also try taking this before bed but you should only do it if all else fails:
Try ZMA..
ZMA is a combination of the minerals zinc and magnesium. Rigorous exercise and stress result in significant losses of these two minerals. A deficiency in these minerals can have a significant effect on strength and endurance.
Zinc is an anabolic element. Therefore it promotes healing, tissue repair and muscle growth. It also increases the effect of Insulin-Like Growth Factor 1, growth hormone and testosterone which are extremely important muscle growth. Zinc is also required for many of the enzymes that prevent lactic acid buildup.
Magnesium helps with oxygen delivery to muscle tissue. It promotes muscle strength, endurance and relaxation. It also activates enzymes necessary for the metabolism of carbohydrates and amino acids.
The body releases the most growth hormone approximately 90 minutes after going to sleep. Since ZMA increases the effect of growth hormone, it is recommended you take it 30-60 minutes before going to bed.

When I took it it made me sleep really well but felt a little funky. I didn't take it long term. Just maybe 2 months or so.
You can also try some melatonin. The pineal gland in our brain controls our sleep/wake cycle (the circadian rhythm). This gland secretes minute amounts of the hormone, melatonin, at night in response to darkness. Supplementing with melatonin will help you fall asleep and keep you in REM (Rapid Eye Movement) sleep longer. This will ensure better rest at night. I use tp take a 3mg tablet one hour before going to bed. Start with only 1mg tablets and only move up the dosages if needed. Again, I would use this short term too if it all possible. Just until you are consistently sleeping better and not so sore.
