Can I reduce 100ml of water to 50ml, with 3ml of CDS?

My dad who has pancreatic cancer has started taking 5ml of CDS with 100ml of water, every fifteen minutes, 8 times in the morning, and 8 times at night. 
The problem is, he is feeling sick and bloated with the amount of water he is having to take. We have reduced CDS amount to 3ml per dose. 
Is it possible to reduce the 100ml of water per dose to 50ml?? 
This is urgent, so I would be very grateful if someone replied. 

Thanks

Absolutely, in my humble opinion. I have at least that fairly often

If he has decent stomach acid,he can also use some drops of sodium chlorite with a small amount of water

Yes.  IMO, the amount of water doesn't matter that much other than to make it tolerable and keep your stomach from rejecting it.

When we get to the higher doses, we will start taking 1/2 as much every 30 minutes or 1/3 as much every 20 minutes instead of the full amount every hour.  Each person tolerates it differently, and you may have to get creative to get to the higher doses.  I can take up to 4 drops pretty easily, but others in my family can barely handle 2 at a time.

I only use about 30 ml of water with 3 drops of MMS, which is roughly the equivalent of 3 ml of CDS (according to A.Kalcker)

RJi. Thanks for replying. 
Why should my dad use some sodium chlorite if he has decent stomach acid? What will it do for him?

Thanks

He could try this protocol.
