Try Diamox before leaving for Nepal. We recommend taking Diamox from start to finish. Ask your Doctor who knows your medical history as Diamox is a Sulfa Medication, so if you are allergic to Sulfa’s, you can not take it!  Our doctors recommend 125 mg in the morning and 125 mg in the late afternoon. This can vary on the person, symptoms and a range of factors. One downside to Diamox is that it is a diuretic, so again, make sure you are staying hydrated if you are taking it.
