If you premix the pepper into the lemonade it will get hotter with time. Again, add pepper to taste. & Don't do P&B shakes while on the MC. It defeats its benefits. If you're doing it just for weightloss then who cares, but the Master-Cleanse produces such wonderful health benefits when you follow it correctly & allow the digestive system to turn off. Since you're doing the Master-Cleanse anyway, why not do it correctly so you can get the MOST out of it? But if you insist on the shakes be sure to drink TONS of water cuz P&B can bind you up.
