Fighting BPD urges

I was officially diagnosed as boarderline about five years ago, and I went through intensive therapy incleading inpatient and DBT, and was found to have overcome the disorder, but sometimes I still have to fight so hard to not fall into the same old habits. For example, sometimes I still impulsively buy silly things I dont need, or despite the fact that I am in a loving, committed, long term relationship, I still find myself wanting to sleep with random people. This is stuff I did before I sought out treatment, and sometimes I feel really compelled to do things I know are a symptom of BPD. Its so hard sometimes to be a functioning adult that makes good decisions when Im fighting this stuff in my head. Anyone else struggle with this?
