Mirtazapine had zero effect on my appetite, or anything else.
I used to take 400mg extended release seroquel, and this did not make me hungry, but i did gain weight. I trialed several other ap's but I'm not sure how much they effected purging, because i was too engaged in it already.
I no longer take psych meds.
Do you tell your pdoc when this happens? Do they help? I hope so.
