File early. The window is shorter than people think and it starts at the transaction. Not on a fee on the statement but the pattern is familiar.

Written confirmation email after every phone call. Cheapest insurance there is.

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

You are not imagining it and you are not being difficult. Document it and take the document in. Not on a closed practice but the pattern is familiar.

Log dose, time and sleep. Ten seconds a day and it turns the anecdote into something you can look at.

Bring a list. Embarrassment makes everyone forget things, including you.

Ask for the longer appointment slot. Ten minutes is not enough for a complex history and pretending otherwise wastes both your time.

Test one thing at a time. It feels slower and it is the only way to learn anything.

This is the correct amount of effort for a thread like this.
