Looks like high levels of IL-6 can induce insulin resistance which could lead to the symptoms some of us experience in terms of metabolic syndrome.

Interleukin-6 induces cellular insulin resistance in hepatocytes.

Abstract
Interleukin (IL)-6 is one of several proinflammatory cytokines that have been associated with insulin resistance and type 2 diabetes. A two- to threefold elevation of circulating IL-6 has been observed in these conditions. Nonetheless, little evidence supports a direct role for IL-6 in mediating insulin resistance.
Here, we present data that IL-6 can inhibit insulin receptor (IR) signal transduction and insulin action in both primary mouse hepatocytes and the human hepatocarcinoma cell line, HepG2. This inhibition depends on duration of IL-6 exposure, with a maximum effect at 1-1.5 h of pretreatment with IL-6 in both HepG2 cells and primary hepatocytes. The IL-6 effect is characterized by a decreased tyrosine phosphorylation of IR substrate (IRS)-1 and decreased association of the p85 subunit of phosphatidylinositol 3-kinase with IRS-1 in response to physiologic insulin levels. In addition, insulin-dependent activation of Akt, important in mediating insulin's downstream metabolic actions, is markedly inhibited by IL-6 treatment. Finally, a 1.5-h preincubation of primary hepatocytes with IL-6 inhibits insulin-induced glycogen synthesis by 75%.
These data suggest that IL-6 plays a direct role in insulin resistance at the cellular level in both primary hepatocytes and HepG2 cell lines and may contribute to insulin resistance and type 2 diabetes.

http://www.ncbi.nlm.nih.gov/pubmed/24231099alpha acids reduce the inflammatory cytokine IL-6 (see this study provided by Richard), and IL-6 seems to cause reduced concentration and brain fog symptoms: IL-6 causes fatigue, reduce ability to concentrate,ᐞ difficulties with memory and learning,ᐞ and cognitive declineᐞᐞ. In short, IL-6 seems to be a sort of "essence of brain fog" cytokine. And studies have shown IL-6 to be elevated in ME/CFS.ᐞ
The cocktail of IL-6 inhibitors I took before socializing were the following:
IL-6 inhibitor Protocol:
Luteolin 100 mg
Idebenone 200 mg
Q10 200 mg
PABA 500 mg
Horny goat weed (Epimedium) 900 mg
Curcumin 900 mg
Vitamin D 10,000 iu
Vitamin E 400 mg
Pregnenolone 25 mg
Vitamin K 100 mg
Vinpocetine 30 mg
Genistein 56 mg
Daidzein 37 mg
Amla 2000 mg
Niacinamide 500 mg
Some study references for above IL-6 inhibitors:
Four macrolides (roxithromycin, erythromycin, clarithromycin and azithromycin) inhibited IL-1β, TNF-α, IL-6 LPS-stimulated J774 macrophages. 1 (full text). NOTE: Roxithromycin is the only macrolide antibiotic that crosses the blood brain barrier.

Vitamin D inhibits LPS-induced IL-6 and TNF-α production in macrophages. 1
Cyclosporin A decreases human macrophage interleukin-6 synthesis. 1
Luteolin reduces IL-6 production in microglia. Luteolin: 90% drop in IL-6 production.1 Pretreatment of primary microglia with 10 and 25 μM luteolin reduced LPS-induced IL-6 production by 40% and 90%, respectively. When luteolin was increased to 50 μM, IL-6 secretion by LPS-stimulated microglia was completely blocked. If we take the bioavailability of luteolin to be 5%, then the dosage to achieve a 25 μM concentration is 25 x 286.24 / (55 x 250) = 520 mg of luteolin. NOTE: the lutein bioavailability when given as Chrysanthemum morifolium extract is 55.4%, but for pure lutein is may be much lower. 1
