Recover database to previous after it is restored from backup file

Question

I have a database db1. I backup this database two days ago and it is stored as db1.bak.

Now I created another database db2 and restored using backup file db1.bak. I made changes to many tables in db2.

Today due to some reasons I restored db2 using db1.bak without taking backup of db2 :(

But now I need to recover database db2 with the rows as of yesterday. I guess this is not possible but for a try I'm posting here.

Note: I'm using Microsoft SQL Server 2008.

If anyone knows the way to recover, kindly help me. Thanks in advance.

Answer 1

It isn't possible. You have lost the changes
