About to run out early

Been on subs for two years, started at 16 mgs but been at 4 mgs for a few months. Unfortunately I’ve been taking 6 most days and my psychiatrist got them to give me early refills TWICE and said that was the last time he could.

So I don’t have a refill for 10 days, and have 4 or 5 2 mgs left. What should I do? I did 1.5 pills yesterday and 1.5 today. Should I just take one 2 mg pill tomorrow, then do half a pill each day? Even then I’ll be out a few days early. Am I in for a really bad time? Level with me here because I don’t know what to expect
