Alcohol makes me so tired now

Hi so not sure if this is okay to post here, please let me know where else I can ask if not, but from around February to April of this year I started doing coke but only when I’d be drinking, it was fun and whatever. I didn’t get addicted to it because it made me feel so shitty after, I haven’t done it since May probably, I have no desire to do it, but I just have noticed something since then. Everytime I drink now I am so tired, like I literally cannot even catch a good buzz without tiredness accompanying. I used to be able to drink and stay up all night even without coke, but since I tried it and it gave me that boost when I was already drunk, now it seems I can’t drink without feeling so tired. I feel like it’s because of cocaine but idk. Has anyone dealt with this?
