Didn't get drunk after finishing more than half of Rockford.. Is it fake? Did i get duped?

Or there's something wrong with me? I drink like once in 2-3 months but this was my first time drinking alone. Setup: Rockford (180 ml) + Coke + Pizza + momos + Garlic bread + ladoo + water + chips + music in the background + in my room Is there something wrong with my setup? I'm so fucked confused, i did not even get a headache, i did not get drunk last night even. Ps: last time i drank this with my colleague, i liked it and got heavily drunk. Since i dont know much about which brand is good, i bough this again. Went to 'The Liquor warehouse' and picked this bottle by myself and bought it. https://preview.redd.it/f6m032g6fz6e1.jpg?width=3024&format=pjpg&auto=webp&s=159bbed5042f793b80f13c731c29ab3e0613b3c7 https://preview.redd.it/p441xvf6fz6e1.jpg?width=3024&format=pjpg&auto=webp&s=03df6aaa7eb538719d6e00ccecabcf05804360e4 https://preview.redd.it/1ovov2g6fz6e1.jpg?width=3024&format=pjpg&auto=webp&s=aa8f14c38687afe9a8a3164da99a28892e3418b4
