Oooh this is interesting. I’m a massive allergy sufferer - it starts early April, runs to late September.
One thing I notice is that it never effects me whilst riding (though sunglasses help, and I wear them all day every day, April to September!) abut the second I stop I’m in pieces.
I see you’re in the UK. Was it NHS? Or can you just buy it? I’m very interested.
Thank you. Personally I have concern that it may interact with other things I have going on, so I won’t be treading anything but extremely cautiously and with appropriate expert advice.
