Okay so i get panic attacks in classroom situations but I also have add so I've been on vyvanse to help me focus which i take at about 6:30 am and it kicks in at 7:30 and lasts me all school day now I am prescribed .5 mg ativan should I take it at the same time or wait until i just get to school to help with anxiety/panic problems in school and will it last the whole 6 hour school day or should I take another in the middle of day. I unsure on how much time it takes ativan to kick in and how long it lasts as I see mixed results everywhere online can someone please help me out or at least point me in the right direction thanks so much!
