For me it works great for now, but in the first few months of usage i suffered from a lot of side effects. It is getting way better now. I get mine from this shop but i dont know whether this does make any difference at all. All in all im quite happy with using melatonin.
Had this thought, too. Also for the transition phase this supplement helped mit a lot against the occasional occuring pain. I can highly recommend it, and would support the OP in his advice.
