Battery health dropping drastically ( iphone 14)

Battery Health drop is no linear and one can expect at least a 1% drop in battery health per month, so your battery is certainly within the range one can anticipate. It can remain steady for a while, drop a point or two. There's only one direction Battery Health goes and that is down. Based on what you've posted, there doesn't appear to be anything to be concerned about. When the day comes that the health of your battery dips to 80%, which it absolutely will, it will then be time to pay Apple to replace the battery.

Until then, things you should do:

1. Avoid letting the battery ever fully deplete or go below 20%
2. Plug your phone in to charge at night when you go to bed and leave it plugged in all night, every night with Optimized Battery Charging turned in Settings > Battery > Battery Health
3. Stop worrying over the natural decline in batteries. It's what batteries do. ALL BATTERIES.

Had this type of issue with my old phone. I had it constantly on Low-Battery mode and it seemed to help a bit, but was never a perfect solution. I would try to keep the brightness down as well, and see if that helps with battery life.

Is it normal to lose this much battery health in just 6 months ?

It is within the normal range, yes.
