i have been taking ibuprofen for like 3 days straight because of a headache. today i took one at 2:30 pm, then another one at 5:30, even though you are supposed to wait 4 hours, but i figured since you can take 2 at a time i'm fine. then i took another one at 9:30, can i take another one now, at almost 4 am, or should i try another method?
