I started on generic Prozac 10mg 4-12-2015 after my father's death & for anticipatory grief of Mom who was rapidly declining. After Mom's death, my doc increased Prozac to 20mg on 7-17-2015, without informing me. I noticed the increased dose after prescription was filled. Anyway, I've really noticed 3 obvious undesired effects since being on 20mg, which seem to outweigh the benefits. These 3 undesired effects are: fatigue, dry mouth & increased perspiration. I'm seriously considering weaning myself off the Prozac, but thought I would first try this forum for suggestions, etc. Has anyone experienced these undesired effects also... if so, any helpful suggestions would be most welcome. Thank you, Cathy
