Reply to Flambaum Commentary [arXiv:0808.2518] on Black Hole Constraints   on Varying Fundamental Constants [arXiv:0706.2188, PRL 99, 061301 (2007)]
  We discuss the Flambaum commentary [arXiv:0808.2518] on the application of the Generalized Second Law of Thermodynamics to derive limits on the variation of fundamental constants, for example the fine structure constant.
