My husband has had bouts of insomnia for the past two years. He might get a couple hours of sleep, but then he pops awake and he cannot get back to sleep - no matter how hard he tries. We do not know what is causing it, but it is certainly making him grumpy.
Then, there comes a time when he has gone so long without sleep that he becomes a walking zombie and falls asleep almost immediately after he gets home. He recently decided to go ahead and give some natural sleep supplements a try - AhSleep. If it was not natural, he probably would not have taken it. He has taken prescribed sleeping pills before and they made him feel terrible.
AhSleep did not put him to sleep immediately, but I can tell you that he did not wake up in the middle of the night. He managed to sleep through the night and feel refreshed the next morning. It has not been every day he took a pill, though. I would say it happened two times out of the three days he has taken it. So, while he is not totally happy with it, he is still willing to try it again. Some improvement is better than no improvement.
