Hi. Are you still facing this issue? I thought of replying as I have seen many people facing such a situation.I hope that I am not too late in providing you a solution. Just clear your mind before sleeping and do not engage your brain with any thoughts. Keep yourself relaxed. You can try to change the sleep environment of your room. If you want, you can buy a new mattress that will provide you a sound sleep. I was looking for a mattress from Palma Sleep for my wife and found this site that has a great collection of mattresses. You can sleep well on a good mattress. Also, have a regular sleep pattern. Leave fears and concerns behind as you go to sleep. I hope these tips work for you.
