About the time I went RAF (approx 4 months ago) I also started on the Dr Rons freeze dried Adrenal with cortex, as I am sure I had adrenal fatigue from years of sugar abuse, mostly chocolate. I was taking the adrenal caps fairly regularly and slowly increased from 1 cap a day to 3, taking them with my morning meat and egg nog (2 eggs, honey, coconut cream or raw milk). If I took them out of the cap and sprinkled them into my egg nog I would experience slight nausea about half an hour after taking the caps, so stopped taking them out of the cap.
But then a few times when I took them I would get quite a severe reaction where I felt like the sides of my diaphragm had been punched or were cramping or something and were on fire. I would feel a sudden onset of pain about 30 - 60 mins after taking the caps, and within a couple of minutes it would really set in, and would take about 30 minutes to subside. The severe pain also resulted in a low blood pressure attack, as well as the need to evacuate my bowels. It took me two or three times of this experience before I worked out it was the adrenal caps, as I realised the pain was originating from about where my adrenals sit.
It was odd that it was intermittent, but I thought maybe it was dose related, so after abstaining a week or two, tapered it down to 2 caps. This caused a reaction also. I decided to give up on them, but then last weekend I tried 1 cap. All went well, so I tried 1 cap again yesterday with meat and a sizeable amount of suet (no egg nog). Again, all ok. Today I took the cap with meat and a little suet, and half an hour later I got the pain. It's left me feeling wiped out most of the day, and not feeling like eating much, save for a little bit of fruit (even though there was no nausea accompanying the pain).
I realise now that the pain probably depends on either the amount of fat I consume with the caps (maybe the fat buffers its release), or the cortex has a build up effect over a few days and my body can only take so much. I need to research this, but I suspect it is the cortex that is causing the pain. I have found virtually no reference to side effects associated with freeze dried adrenal supplements, but I think that is because most of them do not contain the cortex.
Another thing I experienced with the caps when I was taking them regularly was, upon waking, I would feel a sense that something bad was going to happen. I later discovered Dr Lam's website which described exactly this. He put it more succinctly as a feeling of "impending doom". At the time I thought I was feeling that way because of all the noise in the news about the economy. But I went off the caps and the feeling stopped. This article from his site describes it:http://www.drlam.com/adrenalfatiguecenter/7mistakesofadrenalfatigue.asp
One other symptom of the caps I had was that a few times I would break out in little, itchy lumps on my body that would appear within 5 minutes, but then were gone within the hour. The first time it happened I thought a flea was running rampant under my shirt. The lumps were circular and about the size of a flea bite. But then they disappeared without a trace so quickly, and there was not even a hint of itchiness or marking after an hour. It happened today after the pain subsided, only it was only a couple of lumps as opposed to the first time where there were at least two dozen on my neck and torso. V weird. Maybe an allergic reaction, but then why was it far less severe today.
I know that adrenal fatigue is one of the reasons some people are turning to RAF. I figured that these caps would be a close cousin to eating raw, but there's no way I am taking them again, even to experiment with the fat ratio mix. The pain is not worth it.
I read somewhere that low carbs can also put the adrenals under stress, which I can believe. I've done occasional half day fasts and that was really stressful on my system. I don't think it is worth trying to dive straight into a 100% carnivore style diet until my adrenals and other glands are back on track. The saying "slowly but surely" seems to be apt, at least for me. I would be interested though in how others have dealt with adrenal issues whilst being on a RAF diet.
