If you take it 6 times a day every 3 hours it would mean you need to be awake 18 hours a day ready to take doses.
That leaves less than 6 hours for sleep which is very much counter productive for your diet & training.
if you are going to be awake that much then yes, thats completely fine to do... i only sleep 5-6 hours a night so that is something i could do... it just depends on you bro but if you can make it work then that is completely fine
So I work shift work 2 days 2 night 12 hour shifts then 4 days off.
My day shift timings for the dosages are as folllows
0430 5mg
0630 5mg
0930 5mg
1230 5mg
1530 5mg
1830 5mg (then I train 1845 roughly)
Night shift I train before work so timings are
1500 20mg
1800 5mg
2100 5mg
On my days off it's easier.
0730 5mg
0930-1030 5mg
1230-1330 5mg
1530-1630 5mg
1800 5mg train
2100 5mg
