Hey SDH.
Try not to beat yourself up too much. Quitting drinking is hard and you did it for 4 whole months!! That is a huge accomplishment. I have read a few of your posts where you talked about how you were finding sober living hard and that temptation was getting to you. Try to take it as a learning experience that drinking life is harder with little benefits.
We all stumble. Pick yourself up, dust yourself off and keep moving forward
