An Update & Advice on Chest Pain and Nitro Pills

I have written on here before and just giving an update on my latest procedure and I need some advice on how to cope with life from now on.
You may remember, on 2/23/10 I had 2 stents placed in Diag 2 and 1 stent in my Mid LAD. I also had a 100% distal LAD and Diag3 opened.  No stent placement in those locations because they were too small of a vessel to put a stent.  
On 3/31/10 I went back in to have my Ostial Cirmcumflex stented and when inside, they discovered that my distal LAD had re-stenosis of 80% already.  I was told that “this is common” and I figured it would happen anyway from everything I have previously read.  
They ended up using “Angiosculpt” to clean out the distal LAD location but I am sure it will get re-stenosis again.  
I have my nitro pills just in case I get chest pain.  
For the people who have had heart disease for years.  Here is my big question:
Will I just eventually get use to just taking a nitro pill when I feel chest discomfort and going on with my life?  As I also mentioned before, the CAD diagnosis in 7/2008 gave me a panic disorder “when I was 15, I seen my Dad die in front of me from a heart attack when he was 44.”
So anytime I have gotten chest pain in the past 1 ½ years I immediately think I am about to die.  
So I guess from now on I have to program myself that when I get chest pain I will put a nitro pill under my tongue instead of a Xanax?    It amazes me how when you are being discharged from the hospital they tell you.  If you feel chest pain put a nitro pill under your tongue, if the pain doesn’t go away in 5 mins take another, if it still doesn’t go away then call 911.  The make it sound as simple as; brush and floss every day.   Don’t need any advice on the lifestyle modifications, I already practice all of that and I had further progression anyway.   At this point I am considering a non-meat lifestyle.

I have had stable angina (chest pain with exertion) for more than 6 years and take a nitrate (slow acting) prior to an aerobic exercise and that controls symptoms.  I also have the fast acting nitro pill available but seldom used. That works for me.  Have you tried a nitrate?  There is a tolerance issue with a nitrate and it is recommended to interupt occasionally for a day or two.  

For some insight: Different nitrate preparations are often combined. Pills, patches, or paste may be used together with sublingual nitroglycerin to give maximum relief and prevent angina.

Some people develop a tolerance to nitrates if they use them constantly over a long period. Tolerance occurs when a medicine loses its effectiveness and may not seem to work as well. A doctor may prescribe a daily schedule of using nitroglycerin 12 to 18 hours on and 6 to 12 hours off to prevent the development of tolerance.
