Unlike many prescription and over-the-counter drugs, iMusic is not habit forming. Rest easy knowing that you won't become dependent on iMusic or build a tolerance to its effects, because iMusic promotes long term and permanent improvements. If you are new to iMusic, you might want to use it every night for chronic insomnia, or "as needed" for occasional sleeplessness and night time restlessness. Over time, you’ll be able to eventually stop using iMusic for sleeping altogether.
