"Today I had only one patient."

Translation: Astăzi eu nu am avut decât un pacient.

[Diana338934]

Astăzi eu am avut doar un pacient.
(Eu) am avut doar un pacient azi.
Where comes from the negation?

Your version makes more sense and is accepted :-)

"Today I have not had more than one pacient" is quite a roundabout way of saying it.

Same question as Diana

This is unclear!!
