haha... no not at all.. if it really is true bromo it will last 2-3 days in high doses.. in smaller doses like 2-5 hits it will last 24 hours. but most of it is just tweek, the peak will last about 6-8 hours then its just no sleep and jittery for the rest of the time.
the longer a trip the more introspective and meaning ful, i havent had many trips though and havent done anything for awhile so my input might not be right lol
ive taken 2 hits of what i persume weak bromo an it lasted a i took them at about 8 an i went to bed at 4 but i was tired way before 4 i was tired aroudn 2 decent visuals no mind trip horrid taste be perpaired. but it will last a long time when i woke up i was still getting patterns an stuff but you really have to concentrate to get them which is gay.
