Melatonin is involved in the regulation of the sleep-wake cycle, circadian rhythms, and seasonal changes in the light dark cycle. Commonly used to induce sleep, some (but not all) find it to reduce jet lag. There is a high concentration of melatonin in the pineal gland, where it is manufactured. I was surprised to learn that there are significant amounts of melatonin present in the gastrointestinal tract.
In 2014 the average dual fuel reached an eye watering Â£1,344. The average electricity bill was Â£592 and the average gas bill was Â£752. But averages can be confusing. So to give you a better idea of how your own bill compares weâve estimated the total bill for small, medium and large users in the chart above.
Gas was 40-80 (40 in summer, 80 in winter) - amount might be more if you have a gas stove, not sure how much that would affect that. Water was 20-40. Some complexes include water, others don't, but it really varies. Cable on the other hand, for cable TV (with extras) and internet was 120 or 140 (I forget which).
