Back in Papua New Guinea I trained with some friends in a kickboxing club. We had an intense training regime. When I started training 10 hours a week I started getting visual disturbances an hour or so after the training. The disturbances would go away, followed by an intense headache. After a painkiller and a night sleep it would go away.
On Tuesdays I train with some colleagues. I’m now on half an hour cardiovascular training and an hour kettlebell training. Two weeks ago I had the same headache again. Luckily we have a physiotherapist specialised in working with diabetes patients at Physique. She has glucose meter I can use.

So now I’m going to see whether or not my blood sugar levels are within the proper limits.
