Can I incorporate a salt-water flush and the Master Cleanse drink into my normal diet?

I'm on day 1 of the master cleanse now, and I'm wondering if I can make the Salt Water Flush and the MC lemonade as part of my regular diet? Perhaps not doing the SWF every morning, but a few times a week? And perhaps drinking the MC lemonade a few times a day? Or would regular lemon-water be a better option for everyday?
