its all mental man, just keep reminding yourself its temporary.
try to just settle in and just let autopilot take over, if you let stress and anxiety run rampant, spiking cortisol, itll make things more difficult.
dont be afraid to rest and sleep when you need to.
There were definitely days in prep were i was getting home from work, eating, then taking a nap for 30m to an hour before heading to the gym, and then come home just to shower, eat and go right to bed. its all normal and part of the process
The brainfog can be exhausting, especially when carbs first drop to really low or zero when youre not used to it.
Im not usually one to advocate throwing drugs at symptoms, but i had a great experience with modafinil to help manage the brainfog and be somewhat productive at work still
Dont even consider it as an option. youre tougher than that.
itll all be worth it soon.
