First indications for me was low B12, I now have 8 weekly injections at GP surgery. Likely that I don't absorb (saw dietician under NHS). Was so tired once almost fell head first into my tea after work.
Probably due to intrinsic factor production being turned off (genes + ? environmental factor).
Seemed OK for a good while.
Then at age 36 I had a baby that cried and cried and never slept.... survived that somehow BUT
When he was 2 this resolved and then I started asking why my energy was still so low - crashing out etc.
Also had a weird gastro bug, very extreme in late 2013 which I suspect didn't help. Diagnosed 2014.
I have had a good friend who's had it seen being a teen (after her mum died), and she and her dad have spent £££ over the years on snake oil.
I did look into Sarah Myhill, I think she may have some good info. Tried paelo diet/low carb - for weight. She says try not to have sugar/caffene as they are false friends.
I am still friends with them, even though I know this.
Sigh.
Only co-enzyme seems to be effective - if I run out I really notice and the B12 jabs are effective - better now that when they were every 12 weeks. Noticable slump - colleagues and friends could clearly see when it was the week before I was due!
Have gained a lot of weight, now 74 kg which is heaviest I have ever been and its tricky because
comfort eating/stress eating
inability to do any proper exercise - i.e cardio
All of which makes joints creaky - arthritis in hips and back (early stage) so I know I need to lose some pounds, and keep stretching and strengthening (doable).
