Bodymachine,
If I were in your position, I would tackle it from a nutritional standpoint, prior to resorting to a supplementation regimen, by including alot of grains in the diet. I don't know how you're going to do it if you're strict about your carb intake, but 12 grain bread would be good for that.
If calories are a concern, you might want to include celery... lots of it.
Pineapple is good for digestion as are various herbs and tinctures. If you have a knowledgeable herbalist or health food shop near you, they should be able to recommend something that will work without throwing off your routine.
ps - It's quite possible too frequent use of Metamucil and other laxative type preparations might actually be the cause of the problem, and may infact be exascerbating your problem. Over time, your bowels lose the ability to function as they are suppose to, requiring you to purchase even more Metamucil. It's a vicious cycle. Upping the fibre content of your diet is more economical, and it can only be beneficial as far as regularity goes.
pps - you might also want to reconsider the amount of dairy, as well as watching your wheat gluten intake
Hope That Helps,
