Prozac bridge from Cymbalta

Hello everyone. Today is day 1 on 10mg Prozac. My bio will give the details of all the drugs I've been on and am still on over the past couple years. I have been deprescribing for most of this year. Today is day 1 taking 10mg Prozac in place of 20mg duloxetine, where discontinuation symptoms had become uncomfortable. My specific symptoms have been flushing, hot flashes, vivid dreams that disrupt sleep, low energy levels with waves of extreme fatigue, and my forehead and neck get very warm in waves also. Hoping to hear some success stories from similar situations to boost my mood, get advice from people who are in or were in the same situation, and to offer support to those in my situation as well. Any advice or what to expect would be appreciated. I know what the psychiatrist told me, and he has been much more informative than the doctors who prescribed these meds in the first place, but I value the experience of those who have lived it firsthand more than that of a doctor who doesn't really know what it feels like. For extra info, I chose to try the fluoxetine bridge because I was able to easily stop Lexapro in the past. The duloxetine, however, has been a nightmare since getting down to 20mg. I hit a wall and 3 weeks in, the withdrawal symptoms are still intense. Any advice on dealing with the symptoms and what to expect next would be appreciated. Thanks in advance.
