I have a problem with the taste as well. I can't handle the cayenne. I mix the lemonade with everything but the cayenne. Then I put the cayenne in a small shot glass and mix about enough of the lemonade to drink it and just gulp it in one swallow and drink the rest of the lemonade mix like normal. I drink my lemonade within 5-10 minutes of doing this so I figure it mixes in my stomach. I mix mine by the glass but maybe you could just do something like that every 10 oz. if you are pre-mixing in a 30 oz bottle.
The Sea Salt flush isn't as bad as it sounds. I actually have cramping and pain with the herbal tea so I've just used the Sea Salt flush. I drink almost the whole quart. I will start to get really queasy about the last 8 oz. but I stop and about 40-45 mins later it's all running through.
