Hi, I am not on Pred or either of the PF drugs. I had an exacerbation (after 10.5 years) in which I lost my appetite. Food made me nauseous to even smell it. After things calmed down, I had lost 31 lbs. I asked my PCP for something to stimulate my appetite. I am taking Mirtazapine (which is also used to treat depression. My appetite had picked up. I have gained 11 lbs back since November. This worked for me. I also take an extra reflux med around 2:00 pm everyday. Hope you find a solution! Best of luck. Regards
