Ans: Yes, you can sleep after drinking whey protein. Consuming whey protein before bed is unlikely to interfere with your ability to sleep. This protein is known for its fast digestion and absorption. It means it doesn't stay in your stomach for an extended period. However, individual sensitivities may vary, and some people may have personal preferences about consuming any food or drink close to bedtime. If you find that consuming whey protein before bed affects your sleep quality, you may consider adjusting the timing or spacing out your protein intake throughout the day.
