During the taper phase common side effects include (and are not limited to): Madness, phantom pain, irritability, insatiable hunger and thirst, endless worry, and comparison. You will be a dick to your family at some point. You will be self-indulgent and mope in a Zoom call going “No one even knows what I’m going through”. You will stress about your training, and your gear choice, and you will have regrets. You will feel like you are losing fitness. You will question your life choices. 

Don't worry. Matt, Ali, and Andrew have the ointment.
