yeah
also the reason you felt like you had a brick in your stomach was the glutamine most likely lol
if you take glutamine on empty stomach its supposed to have gut healing benefits
so it probably clumps up or whatever, i dont know
i consume 80g of whey, a litre of skim milk and another 150g of fast carbs (usually haribo but sometimes i do half/half with dextrose powder) instantly pre and during my workouts (so during 90 mins), plus leucine and creatine
just easy and convenient and the macros i want plus i get to eat some shit instead of drinking 150g of pure dextrose (what a waste compared to candy)
and yeah if you dont spread the shit out evenly it can feel like a brick, especially cuz dextrose pulls water in your stomach during digestion... gotta spread it out and drink in sips
however it never hindered my workouts
just dont train abs at the very end after the second shake lol
if you have a sensitive stomach just pound a shake before working out, during drink a litre of soda, thats 100g easy carbs and have another shake post workout
profit
