Had a lovely nap after being at the doctor's feel so much better and more refreshed and have more energy it turns out my lack of energy was caused by stress and worrying about my son being sick. The doctor said I'm going to be fine but my electrolyte levels are low and that's causing the problems too so I have to drink stuff with electrolytes in and if needed take the tablets in water, any suggestions what I can drink bearing in mind I'm in the UK and loads of sports drinks are banned.
