Have pretty much a year taken out every evening to get at least at night after a personal blow to rest and be able to sleep the Hoggar. The Hoggar Night act as a sleep aid. I noticed that after about half an hour after taking such began wegzusegeln my thoughts, I fell asleep and slept soundly. Although I'm woken up at night often, but fell asleep again after a short time. After a year I have stopped taking the tablets without problems from one day to another. Had no withdrawal symptoms. Now I take only from time to time a when I realize that the thoughts begin to circle or if I have to sleep on the road in a strange bed.
