I would avoid that much caffeine btw.

Not everyone is a fan of Hooshmand, and some of his info is certainly outdated. Diet drinks are obviously something that should be avoided even though they're allowed in his diet. In general, his info has served me well over the years, and when I follow the 4 F's diet, I do notice an increase in energy, while experiencing less swelling and pain. For someone so nwely diagnosed, it seems especially important.

"Coffee
Coffee should be avoided altogether in patients suffering from RSD/CRPS; to
consider coffee as a simple conveyor of caffeine is naive.
1. Coffee has an acid-based oil that is an irritant to gastric mucosa. It stimulates
the secretion of gastric acidity. Secondarily, the high gastric acidity results in
secretion of adrenalin. The secretion of adrenalin stimulates insulin secretion
with resultant secondary relative hypoglycemia. The end result is tension, a mild
rise in blood pressure, and 2-3 hours later craving sweets because of the relative
hypoglycemia. Obviously none of the above is helpful in RSD/CRPS. The rise in
plasma epinephrine will undo whatever good medications are doing to counteract
the hyperactive dopaminergic system in RSD/CRPS.
2. Coffee is more harmful than caffeinated soft drinks or tea.
3. Mild tea does not cause reactive hypoglycemia and a rise in blood pressure.
4. Tea, if prepared in mild form (not too strong), contains less caffeine. It has no
acid-based oil as does coffee. It contains tannin. Tannin or tannic acid curbs
thirst and results in less demand for further consumption of tea or coffee.
5. Coffee and tea both temporarily raise the body temperature. A few minutes
after drinking coffee, the stimulation of the dopaminergic system causes colder
extremities and a simultaneous rise in systemic temperature. Tea has a much
milder effect in this regard. The cold extremities aggravate RSD/CRPS.
6. Iced tea seems to be the mildest and safest of caffeinated drinks.
7. A patient with high fever is harmed by coffee and helped by tea and lemon
juice. As is the case with home-made chicken soup being helpful to the sick (in
contrast with factory-made red meat type of soup) for unknown reasons, mild tea
has a healing effect and coffee has an aggravating effect in patients suffering from
stress and fever, including stress of complex chronic pain."
