You could notify the user that he drinks too much coffee but the best is to disabled the button with javascript, for example like so:

$("#btnADD").on('click', function(btn) {
  btn.disabled = true;
});

You can use JavaScript.

Attach form.submit.disabled = true; to the onsubmit event of the form.

A savvy user can circumvent it, but it should prevent 99% of users from submitting twice.
