The best way is to use lime. Plug your nose before you even go into the room where the Miracle-Mineral-Supplement is brewing. Then you put about 1/3 a cup of water in and drink it. The less water the better as you will drink less. Then chase it with a full glass of water that is waiting. Then get out of the room and unplug your nose.
If you do it right you won't taste or smell it at all. You'll just notice something is in the water but it isn't bad.
