Low sugars

[Darrenwo]

Question. I had 2 boiled eggs for breakfast my morning sugars was 6.9 dinner time I had a meal replacement drink my sugars was now 4.4. I went home had minced turkey peppers faheta tea no carbs. One hour later about 6pm I had 9 biscuits.ive started to do lots of swimming and go at 9pm do 20 lengths of the pool.when I tested my sugars at 8.30pm I was shocked they had fallen to 3.8mmol/l .well I didn't go swimming because I will make my sugars go up why the low readings does this mean I'm starting to use insulin better? I've started having cold showers for 30 seconds to help brown fats and insulin uterlisation.
