Sorry for the basic question, but how do you actually start one of these diaries?

Half of what people describe as tolerance is a change in the underlying condition, and the two need different answers.

Reference ranges differ between labs, so comparing two reports is close to meaningless.

Imprint databases are mostly US-centric. A confident hit for another market is still a guess. A fortnight in on a pink oval tablet and it lines up.

Loose evidence and no evidence are different, and people overcorrect in both directions. Currently on vitamin D3 myself.

Everyone here blames the drug. Half the time it is the appointment schedule, not the molecule.

Check the register yourself rather than trusting the number printed on the site. Same for me with a debit card, unfortunately.
