I thought I'd give some more info on my health in case that helps with answering my question about liver cleansing...

I'm 23, female, and have been suffering from varying degrees of adrenal fatigue since my early teens. Up until last year my AF was relatively mild (I didn't even know I had it) and I could get by easily enough with a few cups of coffee.

Coffee is a quick way to drain the adrenals.

However last spring things started to take a turn for the worse. I became increasingly stressed with school and emotionally drained from a long-distance relationship. During this time I went on a second course of accutane (I did the first when I was 18), as the stress increased, I broke out in blisters in and around my mouth. I took this as a cue to discontinue the accutane, however, I proceeded to get bronchitis and was prescribed more antibiotics. Finally I 'crashed' in late April when I smoked pot and had a terrifying anxiety attack.

Since that point I feel like my health's improved somewhat, but I can still have really bad days. My biggest health concerns at this point are low energy, brain fog, anxiety (I used to have debilitating anxiety but that has calmed down somewhat in recent months),

Nettle leaf is really helpful with many cases of anxiety since it builds up the adrenals and reduces lactate.

difficulty falling asleep (just as I fall asleep I wake myself up, it's like my brain is a broken record and won't shut off - however this also hasn't been happening as much lately).

Glycine is also good for anxiety and will help slow down brain activity.

The supplements that I'm taking are: 500mg/day of Vit C made from Acerola Berries, 250mg/day Pantothenic Acid, 600mg/day B-Complex (which contains 100 mg Pantethine), 1000 IU Vit D, 15mg of Zinc, and a tsp of cod liver oil.

I've reduced my supplement intake in aims of getting most of my nutrients from my diet, in general I eat a lot of: eggs, vegetables, white meat (of good quality), fruit (esp kiwis), nuts and seeds, oats, plain yogourt, sprouted bread butter and oils (coconut, olive), kelp, nutritional yeast, bee pollen and I make a large batch of chicken stalk about once a month. I also just started to drink nettle leaf tea.

Doing good.

I'm in the process of ordering bulk adaptogenic herbs (Licorice root, Ashwaganda root, Siberian Ginseng, Astragalus root and dried Schisandra berries... couldn't find Jiaogulan or Amla!?), so that I can make my own formula at home. Are there any additional herbs you'd recommend I add? Also do you know the best ratios I should use of each of these herbs when combining them?

You are pretty well covered with your list.  Your diet is filling in the blanks.  As for ratios you will want to focus mainly on the ashwagandha both because it sound like you may also have some thyroid issues and the ashwagandha will help with anxiety and sleep.  So I recommend 5 parts ashwagandha, 3 parts each of Siberian ginseng and astragalus, 2 parts of schisandra berry and one part licorice root.
