Complete abstinence from tea, coffee, tobacco, and alcohol is the only safe course, and the body can recover if given time.

Original passage

In relation to tea, coffee, tobacco, and alcoholic drinks, the only safe course is to touch not, taste not, handle not. The tendency of tea, coffee, and similar drinks is in the same direction as that of alcoholic liquor and tobacco, and in some cases the habit is as difficult to break as it is for the drunkard to give up intoxicants. Those who attempt to leave off these stimulants will for a time feel a loss and will suffer without them. But by persistence they will overcome the craving and cease to feel the lack. Nature may require a little time to recover from the abuse she has suffered; but give her a chance, and she will again rally and perform her work nobly and well.
