How long before you can reasonably say something is or is not doing anything?

Sorry for the basic question, but how do you actually start one of these diaries? Currently on diazepam myself.

Do you contact the customs office or the carrier first?

Following this because I am in the same place and have no idea what to ask at the appointment.

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

Is it normal to feel worse before better? Nobody told me that.

Small wins count. Walking to the mailbox is a data point.
