I learned very quickly that if I eat anything with processed sugar on the label, I feel like I haven't had sleep for days. A prime cause of my fatigue. Orange juice can knock me out for 4-5 hours. Due to this, once learning I had diabetes, I quite radically changed diet.

Doubt exposure to garden chemicals is a problem. I live in a very wild part of the country where I know the farming neighbours, and theirs are sheep farms with very little chemical use. I have a septic tank for sewage so only use very 'gentle' detergents (as you can't risk killing the bacteria in the tank which are needed to digest... well... we'll leave that one as it may be close to dinner time).

After going on metformin, I lost a tonne of weight. Since going on gabapentin/pregabalin, I've put a tonne of weight back on?
