If you were only using for a month... I think you'll be just fine.
Sure, you may feel a little lazy but if that's all you feel... You did good by not getting too far out. Trust us all when we tell you that stopping now is the best thing you could do for yourself!
There are those of us who have chronic pain as using these meds are not a choice. Even then, we cannot use for very long.
The recreational user is another story entirely.
By doing what you did may have saved your life, your family, and your future. God speed.
