Interesting. I have not ever used any of those, but I have recently started to use trazadone, and I've put on weight for the first time in years. I've had stable weight for years, and I'm actually eating a lot less now that I don't use cannabis, yet I've put on weight. Makes no sense, unless it's the trazadone.
I don't have any health problems (other than mental), and I don't use any other prescription meds, or over the counter meds. I can only speculate that my weight gain is directly related to my use of Trazadone.
