Strangely I've had few problems with the effects of panic buying and have nearly always ended up with what I need or something close, so I thought I'd start a positive thread about what can be done to avoid the worst effects.
The DIY bidet: I've got a kitchen bowl in the shower, do my business on the loo as normal, wash and soap in the shower, pour bowl contents down loo, rinse and flush. A bit of a faff but simple and probably more hygienic; I may not bother with toilet roll any more.
Carbs: there are loads of things with high carbs that aren't pasta, breakfast cereal, potato and bread. Broccoli, sweetcorn, beetroot, bananas, apples, and that's before you start getting into PB territory with things like quinoa.
Protein: seems PBs don't eat fish. I mostly eat fish anyway and the occasional steak etc, no problems there so far.
Take-away: I'm on the annual spring diet so haven't made it to the local Chinese yet, but I bet they're very keen to get some customers.
Any more quick wins? The above probably costs more than average, so it would be great to find some cheaper options.
