Day 9 ...please help with minor questions..

1. is it okay to swallow pulp and seed from lemons? i make my drinks fresh and so that sometimes happens.
2. i am planning on an extended fast...hopefully 30 days and am currently taking 4 drinks a day and feeling very good. I am in good general health..just overweight, so do I need to up the drinks to 6 or should i be okay at 4? Has anyone out there done the fast for 30 days or more? I'm just a little scared about how it will affect my health.
3. when you do a Liver Flush is it painful to pass all those stones and ropes i hear about? do they come from urine or bowels?

Thanks anyone who can help me on these.
