BP is one of those things that may take longer - and is not 100% guaranteed <sigh>. My intermittant HBP never remitted on either MMS or CDS, will be honest.
I ended up using Carditone (OTC ayurvedic herbal prep, got it at the health food store. Worked fine for me, although the ayurvedic doc I was seeing at the time (his family actually MAKES Carditone from herbs grown in India) said that for some people who had already been on HBP meds, sometimes Carditone didn't work as well. It has the herb that is used for lisinopril. I've been off it now for 3 weeks or so and should test my BP to see if it has come back up. If it has, I'm going to move to Divya Mukta Vati
Someone here was also recommending Divya Mukta Vati

I can't see from the picture the herbs that are in it, but the things written in the blurb on the page above do not include the same herbs as in the carditone . The person who did the Divya Mukti said that when he went off, his BP did not elevate again, but his pulse went up a bit. (within the norm range) You can read the comments on the page.
I bought the carditone because my doc was wanting to put me on HBP meds and I didn't want to be tied to them for the rest of my life. And it was available here. The Divya Mukta Vati is shipped from India (also ayurvedic), but the postage is free. I had ayurvedic meds for other things when in India and can attest to their efficacy.
Most medications (like our HBP meds) come from herbs from which they've extracted the "active ingredients" - the problem is that there are other ingredients in the herbs that support or modulate the action of that herb, itself. Like taking a whole food vs just a small part of it.
The amount of water is not an issue. You're fine.
