I would not have done anything differently. I started in december, my cupboards and freezer were full by mid february. I stocked up with paracetamol, hand sanitiser, masks, tissues, gloves, soap, disinfectants and toilet roll. None of it stock piling, just prudent preparations, 8 packs of paracetamol, 7 for the virus and one for normal aches. Orders for seeds and gardening equipment were all brought forward, masses of compost bought throughout february and stacked ready for spring planting.
If anything, I would have had my hair cut at 4 weeks and shorter
