Depends how bad you have it really.
Mine's really bad imo.
I have to constantly carry around a toilet roll with me(because a small pack of tissues isn't enough at all)
My eyes r itchy as hell and the temptation is too strong but i've kept rubbing to a minimum
Even when i take hayfever tablets my nose still runs like the wind and my eyes r still itchy, just less so.
I asked the person giving me the stuff why i can't take 2 tablets and they said that 1 should last you a whole day and i be there like bruh this is like 0% strength stuff xD
