cream or butter

Hi! I usually take my triphala right before bed, but I was curious if this was the best time. Should I take it with dinner or on an empty stomach? Am or PM...or both? Tablets or capsules? Starting today I am trying ground flaxseeds morning and night also. I am hoping this helps me have more complete BMs. I am having BMs daily, but very incomplete. I had a horrible cystic breakout (first in a year) last week, so I went for two colonics and released ALOT of icky stuff during both sessions. My skin already looks better. I am trying hard to not use stimulant herbs and stick with the Triphala.
Thanks!!
