With Taking Metformin, I Lost My Weight 0.8kg for 7 Days.

Taking metformin for 7 days, I've lost my weight 0.8kg. Now, it wasn't so bad scary. But my parents' thinking, it may be insufficient. On friday, I ate my favorite ramen with using Uber Eats, so, a moment, my weight had increased. My weight would decrease more if I hadn't eaten ramen. By all means, I tend to relieve my stress by eating and drinking liquor. It's difficult for me to change my personality becoming unstable easily. What the method will I relieve my stress more?
