hi im eric. im from hawaii and new to freediving. im having a problem with my breath hold. the beginning of this week i did a hold of 3 minutes and 5 seconds. today i could not get passed 2 minutes. i was wondering if the beer i had earlier might of caused a negative reaction? Or if it was my workout? did cardio and light lift session and protein shake after. sorry if i sound stupid. not achieving my previous hold has just been killing me mentally.
