Long Term Use of melatonin

[Guest guest]

Anyone used melatonin for years to get to sleep? I had read somewhere that

there hadn't been any tests done on how long-term use of melatonin affects the

brain and how it works in helping us sleep. So this particular doctor/author

did not recommend long-term use. This was a few years back. So I wondered if

anyone has used it for years and is suffering no side effects from long-term

use?
