I use whatever beer or lager is cheapest!, I used to use Asda Bitter which were 4 for about £1.50 but they’ve not had any recently. This week I got 18 tins of Carlsberg for £11 and 4 bottles of Schweppes for £1.30 a bottle at Tesco.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
