the expression of gratitude

Hello

I'd like to ask about the expression of gratitude.

1) You've been very kind to me. I cannot thank you too much.

Is this expression Ok? Is " too much " correct?

If it's not, would you tell me the right way?

Thank you. :)

You have been very kind to me; I can't thank you enough.
