  We study the local lattice integrable regularization of the Sine-Gordon model
written down in terms of the lattice Bose-operators. We show that the local
spin Hamiltonian obtained from the six-vertex model with alternating
inhomogeneities in fact leads to the Sine-Gordon model in the low-energy limit.
We show that the Bethe Ansatz results for this model lead to the correct
general relations for different critical exponents of the coupling constant.
