So I've just recently started taking Vyvanse a couple of days ago, I started on 30mg (It's been 6 days so far), and I've found that it has made no difference whatsoever. I haven't noticed a difference at all in appetite, sleep, attention, concentration etc. For reference, I've been taking it with my breakfast every morning around 10am before starting my classes.
After reading and doing some more research, I've discovered that effectiveness is reduced in women during the time frame of before their period or at the start. I was just wondering if it might also result in a late period or a general delay? I was meant to start my period 9 days ago, and before starting the medication the number of days my period was late was pretty normal, but this is my first time experiencing this much of a delay in my period.
Has anyone experienced anything similar? Is this normal? Could the lack of difference also just be a dosage issue and unrelated to my period?
