I’m also finding improved energy levels - and I definitely did not eat properly pre-Huel! (Honestly, not eating that well now (biscuits are my downfall) but at least a lot better!). Vitamin intake is probably a part of it as well.
I am doing a lot more physical training than previously, and I suspect that the movement and activity helps - the combination seems to be doing wonders.
And as for you, Tim…5am certainly does exist; we just wish that it didn’t.
