So I am planning on taking 12-18 months to ride a bike around the world. Just booked the first flight on the weekend so my adventure begins on October 7th. Getting prepared though and have one issue to address... I have an issue in that I have something called Hashimotos disease or Hypothyroid. I have to take medication every day or my thyroid hormone will drop. Your Thyroid is like the throttle on your body for those who don't know... so if I stop taking the medication it will be like slamming on the brakes on my body and the result is no energy, depression and endless tiredness and if left for say 6-12 months with no medication eventually I would likely die from a heart attack. The latter unlikely though. The problem is that the medication needs to be refridgerated below 6 degrees celcius to be kept indefinitely. Once in room temperature <25 degrees celcius the medication will keep for a cumulative total of 4 weeks before the active ingredient starts to break down and potency is reduced. I can get about 8 months worth in advance before I leave and can probably get some more in the UK about half way through my trip by jumping through a few british hurdles. So whilst I can keep the medication above 6 degrees for some periods it would be better if I could reduce that time by carrying it in some sort of cold case on the bike. So I need some way to store this on the bike and looking at something like this on the link below and rigging up a DC adapter to the bike and back to the cooler. http://www.medicool.com/diabetes/diabetes_travel_medicooler_fridge.php Does anyone have any experience with this at all? Perhaps someone with diabetes that needs to store medication. Ideally I need a cooling device that can run off DC 12V/mains power with adapter/batteries.
