Story recomendations Please - Body Take Control

Looking for suggestions on some stories.
Tried the categories but get too many results.

I like stories with a full change (Science, magic, Hypno etc..)
Where the protagonist isn't happy with changes but the body takes over (or they are forced somehow).
"Only a baby machine" was one story I liked.

I asked a similar question about 2 years ago and it started a long discussion about stories of this type and writing styles.
If you want to comment on that subject, here is the link

But what I really would like is some suggestions of stories.

Thanks in advance for the suggestion.

Also, if there is a better forum here to ask this question let me know.
