"i have been taking trazodone for nearly 18 years. for the most part of this period i have taken 150mg dose. i have never experienced any severe side effects on this medication. however if i miss a dose, i have incredibly bad nightmares and very agitated. to a lesser degree whilst taking these tablets i have a very dry mouth, slight dizziness when standing. the positives are a slightly lifted mood and reduced anxiety. 

more recently i have been prescribed 300mgs, this was to help with anxiety and extreme depression. the increased dose worked brilliantly for the anxiety and depression, however i experienced priapism and was reduced back to 150mg."
