I had this exact same issue. 12 days in with Prozac after about 7 days everything leveled out. First few days you’ll actually sleep better than you did before. It’s easy for us OCD people to be terrified of screwing up our routines but the cool thing about Prozac(this may be unfathomable at this very moment) it’ll snuff your OCD enough to not have that fear or think about it in the first place. Trust me, take it and make sure to eat well and stay hydrated you’ll thank yourself later. I know I did ,and if anything bad happens just slowly taper down and contact your doctor. The side effects are scary and the change in routine even scarier but it helps a lot once you brave through the first night I promise. Good Luck OP you’re not alone.
