PF, perhaps you should get into the habit now of organising your medication so you feel confident doing it when the family are away.
I keep mine in a tin. I know what to take when but perhaps you could write a list of what you take when and put it with your medication. Then set a reminder on your phone for the times.
For example mine would be
Morning: 1 venlafaxine
Evening: 1 fluoxetine, 2 quetiapine. And now every other evening, quarter diamox
As and when: 1 loperamide.
Its good to know your own medications, I am asked at every appointment what I take and I always need to check for interactions when I start something new.
