Schrodinger's Lent

I decided to be boring and give up unnecessary snack foods for Lent, as much for the benefit of my waistline as my soul. The "unnecessary" is there because I actually do have the occasional medicinal use for biscuits, crisps and ginger beer, i.e. treating migraine nausea.

It's only Ash Wednesday and I have already had to invoke the medical exemption, courtesy of some eye tests this afternoon. I think I shall go and find something not back-lit to look at for the rest of the evening.
