I know the altitude sickness has been covered extensively, but my question is more about timing. Hubby and I will be flying in to Cusco from Puerto Maldonado and going down to the SV for the night. The next day we are touring SV and taking train to AC. Following day is MP with a late train to Cusco. Then a couple of days in Cusco before taking the Inka Express to Puno. We've both got prescriptions for Diamox (125mg for me, 250 for him) with instructions to start the day before going to altitude and continue for 2 days. We have only enough for 3 days. My question is should I take before arriving in SV or wait and take the day before we return to Cusco so we are getting the benefits at the higher altitiude.
Any insight would be appreciated.
