From what I know, the key is to have as little as you can in your system food-wise to prevent the risk of vomiting. I don't know if masking the taste is something many people have experimented with or what would be best.
With SN basically being curing salt, it would just be like the taste of swallowing a bunch of salt at once.
If that seems too overwhelming of a taste, you could try using a straw to drink it.
You could also hypothetically take benzocaine to numb the feeling in your mouth / taste buds. Using mouthwash prior to using it could also potentially help. I don't know if using something like a flavor mixture / hydration booster you would put in water would have any effect on the SN's reliability or effects.
This is all just speculation on my part.
