I'm a really bad sufferer too - but a combination of really dosing up on neoclarityn, beconoase nasal spray and sodium cromogulate eye drops, and having spent the past month stuck inside revising for exams means it hasn't affected my anywhere near as bad as normal yet this year.
In previous years I've only taken the tablets et al as and when I felt I needed to, but this year have made a big effort to stick to exactly what it suggests, and started early, in May.
Hope it eases off soon for you daffidazey - I sympathise greatly, as know how awful it is!
