Patients with M.S may have reduced melatonin production, which can cause sleep disturbances accompanied by balance problems.
6 mg of melatonin before sleep can help improve these problems. Worth trying!

A good choice can be

NOW Foods, Liquid Melatonin, 2 fl oz (59 ml)

NOW Foods, Liquid Melatonin, 2 fl oz (59 ml) 40 drops before sleep [see the bottle!]

or


Life Extension, Melatonin, 3 mg, 60 Vegetarian Capsules 2 capsules before sleep
