Since we're talking D3 here, you might want to consider the anti-inflammatory "full monty" that Batch has recommended in critical situations:
QUOTING HERE FROM A POST BY BATCH: "The Antihistamine Full Monty is a collection of supplements with antihistamine properties that include 3 grams/day each of Turmeric (Curcumin), Resveratrol, Quercetin and Omega-3 fatty acids. It also includes 200 mcg/day Selenium, 8 grams/day vitamin C and 10 mg/day Melatonin taken at bed time.
I buy the bulk powdered vitamin C in 1 Kg bags and stir 2 level teaspoon measures in 8 ounces of water and take sips all day until it's gone by bedtime. This is the least expensive form of vitamin C and dosing throughout the day is best as our kidneys filter vitamin C rapidly.
I realize this is a boatload of pills to take, but the Full Monty is proving to be very effective in achieving a CH pain free response. Most CHers respond to the Antihistamine Full Monty during the first week. When you've experienced a sustained CH pain free response for at least a week, you can lower the dose of the first four supplements to 2 grams/day. I'd stay at that dose for at least two weeks then taper the dose down to 1 gram a day. You can skip the selenium and melatonin at that point, but I'd still take at least 4 grams/day vitamin C as it's so important for good health."
Back to me: Red eyes are definitely a possible Covid symptom. You can just google [covid red eye] and see plenty of reports about that. And severe headaches are also a common Covid symptom. So it could be that that is what this is all about (fingers crossed). I'd be careful about increasing your verapamil, for three reasons (these are not hugely strong reasons, so you might decide to do it anyway, but maybe they are worth considering). (1) it's generally not considered a good idea to increase verap dosage without a doctor's involvement; (2) while that level might not, or even probably wouldn't, affect busting, the lower the better just for better assurance of full busting results; (3) as with point (1), it's my general understanding that it might not be wise to go up a notch on verap dosage and then go down when the crisis has passed.
Could you do a SPUT (small piece under the tongue) if you get hit, or even as a possible preventive? It's my understanding that one SPUT, just a pinch of MM, can stop or reduce an attack but won't interfere with an upcoming bust. That could also be a chance you don't want to take, so I'm just throwing it out.
