I have tried everything for my insomnia, had all the tests, and im disease free. i now take melatonin every night for 6 months, is it safe to continue?

Although it is: Optimum not to use long term - it is safer than many other alternatives. But, i would encourage you first to try using really good sleep hygiene. 1. Keep regular bed ; wakening time (includes weekends). Get up same time daily. 2. Make a regular, relaxing bedtime routine: warm bath or shower, aromatherapy, reading, or listening to gentle music. 3. Sleep in dark, quiet, cool room w comfortable >.
