Thanks for the idea. I did a bit of looking and while it's not advised for most, there's a report of two cases who had cutaneous reactions to the vaccine, yet needed the boosters. The docs had them premedicate with antihistamine and take one for 5 days afterwards and it decreased their reactions. I already take 4/day, but can take morning dose right before and add a type 1 at bedtime for 5 days.
