few dosing questions for a wedding im going to later

[spypilot]

i have two 54 mg methylphenidate pills (i believe they are extended) and three cotton sticks of propylhexedrine (170 mg each)
i ask this here because i cant find a chart of how long doses of propylhexedrine lasts so im posting this hoping one of you guys might know from experience
i need to stay up from 6pm to 2 am so if any of yall would be able to tell me how far or close apart to take the doses that would be awesome

I know nothing about propylhexedrine, but if it is anything like pseudoephedrine i would be very reluctant to take it together with large doses of methylphenidate. For me, personally, 54 mg Ritalin at once eould be painful, while 54 mg concerta would be just about right for staying awake on a long haul flight. But everyone’s experience is individual.
