My anti D pills did nothing until I quit drinking. The change after that was dramatic - in a couple of weeks my mood had improved dramatically, and then I understood that alcohol was making me mentally ill. It wasn't helping, it was the cause of most of my issues.
Give this sobriety and your medication a chance. You won't regret it. Drinking, on the other hand, always led to regret. I hate regret.
You deserve better than this, I know you do. So go get it, alliHK. Onward!
