Had been taking Pristiq (50 mg) for over a year; it worked very well, no noticeable side effects. No longer have insurance and cannot affort Pristiq any longer, so my dr. switched me to Oleptro (trazodon) (150 mg). Have taken other anti-depressants, which mostly made me tired; Pristiq did not. Has anyone had experience switching from Pristiq to Oleptro? I really don't want to be tired, or feel drugged all the time (as with Zoloft) or gain weight. Thanks for any help.
