So, the CRS had me only taking two doses of Metamucil a day, and the nefidipine lidocaine mixture. I called yesterday to ask, as I am still in some pain. Primarily, the initial stool is really the only hard part at this point, but it's enough to cause pain while sitting for the next few hours.
They recommended Colace, but it doesn't sound like many folks have had much success with it. If you did, please let me know, as that would be reassuring. 
I took Miralax awhile back, and it was making me have to use the bathroom more often than normal, which made me more irritated. When I told the nurse this on the phone, she said to move toward Colace, because it's main purpose is to be a stool softener, whereas Miralax is just a laxative. However, it sounds like a lot of you had have had success with using Miralax for a softener? If so, I might try the Colace for a few more days (on day two) and see if I notice any change. If not, I might start mixing the Colace and Miralax, like my nurse suggested.  If I do this, do you all think I should still continue to take my two daily doses of Metamucil as well?
Also, I am interested in this ingesting a teaspoon of olive oil in the morning.  Ugh - it's so frustrating! I never had a problem with having a "normal" bathroom experience until the day I developed the fissure - then it all went downhill. 
Thanks for all of your help and advice. This board is really a great resource!

zvee26, wish I can offer you more advise on this but when my fissure was fresh my doctor recommended that I take two spoonful of mineral oil to make things easier to pass, mineral oil is not digested by the body so it goes directly to the bowels.
I later change that to coconut oil raw. Now when it comes to Metamucil I was never able to take it due to making the stools thicker and that makes the BM worst.
I always see the experience of dealing with a fissure and the BMs like a trial and error thing, you have to experiment until you find the right balance.
I hope you find something that works for you.

...two doses of Metamucil a day...
That's a lot of Fiber.  I think you should start counting your daily fiber intake.  For women, it is 20-25 grams and should not exceed 30 grams.  Also, some Metamucil products are fortified with calcium and iron (written in fine print).  If your calcium (contracts muscles) intake is higher than normal, then you need to balance it with a daily intake of magnesium (relaxes muscles) supplement.  Please note, while you are on magnesium support, the intake of laxative products need to be cut down to minimum.
...nefidipine lidocaine mixture....
The use of this is highly recommended to prevent infection and reduce inflammation until the cut is healed.
...the initial stool is really the only hard part at this point ...,
Two possibilities.  
1) The tip of the stool is hard due to incomplete bowels.  Incomplete bowels, on the other hand, can be due to hypersensitivity or pain.  The little poop that is left behind during the previous elimination process, gets harder and scrapes the colon wall during its next round of exit.
2) Too much fiber with too little fluids.
...I took Miralax awhile back, and it was making me have to use the bathroom more often than normal....
Apparently,  Miralax is the best stool softener right now in the market.  One cap at night is all you need to take once you start with the right amount of fiber regime. You may be going more than normal, due to the fact that your bowels are not completely evacuated in the first round. This then triggers the reflex signal and result in more than one BM.
....Colace, because it's main purpose is to be a stool softener, whereas Miralax is just a laxative...
Both belong to the category of fecal softeners.  I think Miralax is hyperosmotic (Polymer type) whereas Colace, is emollient (Salt type).  The only advantage of Miralax over Colace, is that it could be used on a long term (strictly periodical) basis.
... I am interested in ingesting a teaspoon of olive oil in the morning
A wonderful idea!   I would recommend a tablespoon (tsp is too little) each with lunch and dinner.  It should be introduced gradually.  I have been taking two tablespoons each with my two large meals.  Can't go wrong with Olive oil ! It should be organic, EV, uncooked, and first cold pressed.

The term "periodical" is well explained in the following website.
"Miralax can be used periodically long-term. It should only be used for 14 days with a 2-4 week period of abstinence between use" [url=http://web.pdx.edu/~sujata/FruitEze/education/laxativ[color:307c=54126A]e/medical_warnings.html]http://web.pdx.edu/~sujata/FruitEze/education/laxativ[color:307c=54126A]e/medical_warnings.html[/url]
