tdgeek: Pills etc will work, but if you can add melatonin sourced foods that may provide a more consistent outcome
Bickford's cherry juice off the shelf at paknsave about $8 for a litre.Throw back 30mls per night out of the fridge just before bed. Starts working for consistent sleeps after about three or four days. I had all kinds of weird dreams after a while maybe that's just me. I buy it occasionally. It was better than not sleeping.
Over a period of time I tried a few relatively expensive cherry juices and actually that's the one that worked sitting on the shelf at paknsave.
