Hi,
I'm glad you posted about this.
Recognize the addict voice for what it is. When you hear it, recognize it, let it go and move on. Remember it's not you. You've worked for 4 months to be where you are today, and it's likely that the addict voice is picking up strength as this 4 months anniversary arrived.
Go out for a walk, keep listening to good music, call someone, do whatever it takes to get through this funk. You can do this!
