You're going to be a great Dietitian Lisa! You're absolutely correct! Just note, monilite,that when you grind the flax seeds into powder (by using the milling blade), then you not only enhance the availability of the healthy oils, but it will also go rancid much faster. So, be sure to store any left over flax powder in the fridge sealed tightly.

For regularity...A few suggestions that have helped others are:
1) Drinking plenty of water when there's an increase in fiber. Maybe trying some herbal peppermint tea, Tulsi tea, green tea, or ginger tea as this has laxative-like properties.
2) Be sure to include some type of light physical activity - the blood flow and movement stimulates GI motility.
3) Add in some ground flax seeds (like you mentioned) or psyllium husk (this may or may not be a good option as it can either help push things through or potentially clog you up more).
4) Pure prune juice! 8oz 1x/day, then if that doesn't work go to 2-8oz cups one in the morning and one at night.
