I don't think there is any reason to be scared. As long as you refrain from caffeine and take your dosage at the same time each day, you should be fine. It's my understanding that as long as you stay within the prescribed dosage it can't do much harm. The idea is that it gives the adrenals a bit of a break so that they can repair without giving them too much of a break so that they totally shut down, which is what high doses of hydrocortisone does. Have you made any other changes to help your adrenals heal? Has this been something that you have had for a long time or is it fairly recent? Also, how is your water intake? I truly believe that water can help solve many problems. Check out this page
