jdub1980,
Like Matrix says you do need to find out it anything is wrong with you that can be eating up your Cortisol levels and you are low your Dr. is a labs range junky to many Dr.'s look for us to be in range and tell us we are fine. They don't listen to use when we tell them how bad we feel they just say your in the normal range your fine.
Them kind of Dr.'s are not anygood and to many of them do this. If you can find a better Dr. run more tests and if some thing is wrong stressing your Adrenals lowering your Cortisol levels and you fix this your going to get better levels.
People that don't need HC meds going on them it only shuts down your Adreanls even more so you will need more HC meds. I get people going on HC meds that don't need them and they feel worse. Why because the HC is slowing down there Adreanls from making Cortisol.
If you find nothing wrong and need to go on HC meds or Isocort you need to be on enough of it to support your body so your Adrenals can rest and heal then in about 6 to 8 months try coming off the HC meds to see how your Adrenals are working. You need to be off HC meds of Isocot a good 2 weeks to do labs.
We do labs for Cortisol on HC meds to only tell if your taking to much and shutting down your Adrenals the levels you get are not so much true levels but show the Dr. your Adrenals are not shut down and still working. The following is a good link about this and in this is a FAQ's about Adrenals that I helped make full of get info.

Going on HC meds if you need them is safe and you should treat your Adrenals first then after your body is supported go on Thyroid meds you can tell when your supported by taking your temps avg. and when this avg. stops going up and down more then 2 tenths your supported. It's best to start on Thyroid if doing NTH meds low and go up slow so as not to stress your Adrenals even more.
Read this link on how to take your temps and chart them to get your Adrenals supported and how to go on Thyroid meds and how to up the dose.
