King J,
There are many and various sleep aids available from any pharmacy. Most of these medications contain antihistamines, which induce drowsiness by working against the central nervous system chemical histamine. Talk to your doctor before taking any OTC sleep aid if you’re currently taking a prescription monoamine oxidase inhibitor (MAOI) or did so as recently as two weeks ago. Also check with your doctor first if you take any drugs for depression, psychiatric or emotional conditions, or Parkinson’s disease. Melatonin is often found to produce successful results. But as mentioned above, you should check that it is compatible with any medications that you currently take or are likely to take.

ALL ANSWERS SHOULD BE THOROUGHLY RESEARCHED, IN ANY FORUM AND ESPECIALLY IN THIS ONE. - MANY ANSWERS ARE FLAWED.

Do not take anything with side-effects. Generally, anything that knocks you out is not good as it is unatural.
Seriously, try to find something relaxing to do. Try to stop worrying too much.
I found that drinking herbal tea like Dr Stuart’s Valerian Plus really does help you to sleep. I always have a good deep sleep and wake up early in the morning without that ‘dopey’ feeling you get from over-the-counter pills.
Vitamin B12 is excellent for your nervous system and helps you to sleep well.

It is so frustrating to not be able to get the healing sleep your body needs, but do you want something that knocks you out or do you want something that works naturally with your body instead of against it? If you want the former then I can’t help you, but if you want the latter you can go to your local pharmacy and buy something called Melatonin. It generally comes in 3mg and 5mg doses. You should take 3mg to 6mg to start, then an additional 3mg to 5mg per hour until sleep is achieved. A study has been done where 500mg was taken daily for five years with no adverse side effects, and while I do not recommend taking this amount, you should be fine if you need to go up to 50mg or so.
In addition to Melatonin, you can drink Chamomile tea. Your local grocery store should carry Celestial Seasonings Sleepy Time Tea, or Sleepy Time Extra. You can safely drink this in addition to the Melatonin with good results. Sweeten with local honey and lemon to taste, and *no* table sugar.
As with any medication, you need to exercise caution when using these products. Do not drive, operate machinery, or make potentially life-altering decisions until you know how your body will be affected.
You also need to make sure you are eating good, whole foods, fresh veggies, and reduce your fat intake. Get good exercise daily. Find natural ways to relieve your stress, and when you want to sleep, do so in a dark room rather than falling asleep with the t.v. or other light source on.
If the sleeplessness is temporary, these changes should do the trick. If it lasts more than two weeks then you probably need to see a holistic doctor for further diagnosis.
You can also go to http://www.naturalnews.com and search insomnia. You will find a wealth of reliable information there.
Good luck and sweet dreams.

If you ask for Somnil it isn’t fantastic but it kinda works if you take two.

i have had the same problem and asked the pharmacist what he would recommend. he said to take some antihistamines, the ones that make you drowsy. also i sometimes get Avomine, it is a travel sickness tablet which makes you drowsy. there are some over the counter herbal sleep remedies but i thought they were useless. if you can go and see your doctor he may prescribe you some short term sleeping tablets, but they aren’t to be used for a long time as they can become addictive and they stop working if you take them all the time anyway. if you explain that your lack of sleep is affecting you during the day, i don’t see why you shouldn’t get a prescription, though a lot of doctors don’t like giving out them. but they do have their place when needed.
