Eating too many tomatoes!
Didn't think it was possible but just got a message from my family doctor to lay off tomatoes because my potassium level is far too high. Have to call him and explain that it's not a dire indication - just the result of having tomatoes two or three times a day for three months.
We had a killing frost last Friday night so only have another ten days of them left to ripen indoors. But I will give them a miss until next week and more tests. Sigh!
