Has anyone switched 20mg Paxil to 20mg Prozac?

I'm quitting the paxil and taking the prozac every 2 days for the first week, and then every day. Nervous cuz I'm afraid I'm gonna have rough withdrawals. Any advice and has anyone else been through this? I take 150mg Wellbutrin too. I am quitting the paxil because it's making me sleepy and people are saying I am forgetful and demotivated lately and that I've been different. Praying this change helps with my depression... Paxil works great for my anxiety but not my depression.
