oh wow, where to start. Firstly, we don't get premixed HS over here in NZ, i mix it myself and store it in the syringe and have been told to keep it in the fridge. Now i'm wondering if this is correct. When i warm it up in the nuke, i do so when it is already in the nebuliser cup.
I'm not on Tobi, so this part is irrelevant to me, although i am on Pulmozyme but don't bother warming it at all, as it isn't irritating anyway.
This morning i just took my HS out of the fridge when i first got out of bed and nebbed it half an hour later and Mel was right, the chill was off it and it wasn't irritating at all.
