Question about dry cutting to a Liquid D taper

[[Ta...]]

Hi Valium/Diazapam group.  I have a question.  I have been mictro dry tapering from D.  I started at 20 mg and I'm making my way to 12. 

I am considering switching to a water titration when I get to 12.  However, my current doses are uneven.  I currently take pill form ( 4 mg am, 1 mg afternoon, almost to 7 evening).    How many times should I dose with water titration?  Would it shock my system to move to water titration (example 6 am and 6 pm) or (4 am, 4 afternoon, 4 pm)?  Thanks!  TG
