Pulse diagnosis takes many years of training, you will not be able to get much from it without the training. However iridology might be much easier and reveal far more. I will warn you that your Kidney Qi is almost certain to be weak and show a marking in the kidney zones of both eyes. This DOES NOT MEAN a Kidney problem. I must point that out because it relates to the nervous system within the kidney and also a brain area relating to mood and indicates your stress response.
CFS is a condition of excess Yin and anything which can counter that will be of benefit. That includes eating a more Yang diet rather than a Yin diet. Fruits and above ground vegetables are Yin in nature whereas below ground vegetables and Animal meats are beneficial, ie more Yang.
The best results I have got are from German chamomile essential oil, a dropper bottle of 20 to 25ml and half fill with mineral/filtered or distilled water and then add ONE drop of German Chamomile essential oil [eo]. Then get a glass and shake the dropper bottle as vigorously as you can and quickly draw up the liquid and add ONE drop of that watered down oil into the glass. If you add the oil to a dark liquid such as a little blackcurrant juice you will see the oil float and you can judge how strong it is as it will reduce over time as you use it. You will need to judge when to top up the dropper bottle back to 1/2 full and add another drop of German Chamomile eo. I do it about every two weeks so a small amount lasts quite a long time. It does need to be pure German Chamomile eo, you must be certain of that.
You can use tongue diagnosis to guide you. A tongue with a thick coating indicates excess Yin, tiredness etc whereas a Red tongue with little or no coating indicates high energy levels. You can take too much of this so start slowly with one drop from the watered down dropper bottle and you can increase to two drops but I would not go any further. Instead, increase the frequency of consumption. It will take about 1.5 to 2 hours to take effect and it might change the tongue a little, making it look redder below the coating which may reduce a little. This could make your eyes redder and a little bloodshot. A small amount of Aloe vera mixed in can lessen this and I do mean small amount, 2 to 3 ml. I used to use a disposable 10ml syringe with a plug that fits into the neck of the Aloe vera bottle, the syringe should contain the quantity of air that you intend drawing up and then invert it all and push the air into the bottle and draw up the required Aloe so that you know precisely how much you are using. The syringe/plugs are available on ebay.
