Off Prozac after 10 years

[u/HealthCurious1137]

I was on Prozac for about 10 years at 40 mg. After having my first baby, going to therapy consistently, and feeling like I was finally in a good place with my anxiety, I decided to gradually taper off.
I’ve now been completely off Prozac for about 4–5 months. The first 2–3 months honestly weren’t too bad, but recently I’ve started experiencing some really strange physical sensations.
The best way I can describe it is a subtle dropping or sinking feeling in my chest, almost like that feeling you get when you’re about to fall off a cliff or when an elevator suddenly drops, except much less intense. I also experience an internal buzzing or vibrating sensation throughout my body, along with occasional lightheadedness. These feelings can come and go for hours, and they’re really difficult to explain.
Before anyone suggests getting checked out, I want to mention that I’ve dealt with pretty severe health anxiety in the past, which is why I originally started Prozac. I’m already in contact with my doctor and currently wearing a Zio heart monitor to see if these sensations are related to my heart rhythm.
I’m mainly curious whether anyone else who stopped Prozac after being on it for several years experienced anything similar, especially months after stopping. I was on it for such a long time that I’m wondering if my body could still be adjusting, even after 4–5 months.
I’d really appreciate hearing from anyone who’s had a similar experience. Thank you!
