I typically only sleep 3.5 to 4.5 hours per night. I fall asleep just fine, but I wake up in the middle of the night and fail to fall back to sleep.

I believe that drinking large quantities (between 0.5L and 1L per day) of milk will cure my sleep maintenance insomnia, for the following reasons:

1. Milk contains tryptophan, which is used by the body to produce melatonin

2. Milk also contains iodine - indeed, in the UK where I live, it is the population's primary source of iodine, since our salt isn't iodised, unlike in the US. If I have been iodine deficient, my pineal gland may have been uptaking fluoride instead from e.g. my toothpaste, or bromide from pesticide contamination of my food, and this would cause my pineal gland to malfunction. I do frequently experience subjectively cold body temperatures at room temperatures ranging from 20 to as high as 24 degrees Celsius, and struggle to lose weight, both of which seem to me like they could be related to an iodine deficiency issue.

I intend to test this with lacto-free[*] milk over the coming days and weeks.

[*] I am lactose-intolerant
