So tired?

Woke up feeling super exhausted. Took my 40 this morning, an hour later had some coffee. This is my normal routine, I don't eat with it cause I've found it makes it less effective. I usually feel much more awake and focused/productive after it kicks in and I have my coffee. Today it's like the exhaustion never went away. I still feel extremely exhausted 3 hours later after taking it and having coffee. I also take vitamins at night before sleeping. Idk what's going on... Its from the same bottle I've been taking so its not like a difference in batches. I took a propranolol yesterday which i dont usually so maybe? Idk.... Its almost like it did nothing IDK 😭 I was excited too as i have nothing to do today so I was excited to get my house together and clean but I feel like i can barely stay standing for very long and my eyes are so heavy.
