"this worked well for my chronic insomnia for several years, minimal side effects,  then i developed tolerance and eventually the doc jacked the dose up to the max (for hospitalized patients!) . i ended up hopelessly dependent on trazodone (as in addicted) and had to go through brutal, prolonged detox. i would guess doses of 150 mg and below are likely not a problem for dependence, but if you need more than that, i would go a different way. and never escalate the dose the way i did. that way madness lies."
