Seriously? Try different pharmacies. I usually buy it there without being even asked for a prescription. Also Metformin, Piracetam and T3. The place I usually visit in Karnataka sees a lot of Russians, seeing them returning home with bag of benzos, or tripping on ketamine*** (though with ketamine some pharmacies would refuse).
***with which I don't want to offend anyone: And I'm sure Austrians like me, in groups at some hollyday-location would misbehave too.
If where you are, pharmacies really tightened up, you can always go to an Indian doc to get it prescribed.
