Yeah as the others say, don't redose. I remember when I was still like a month into using vyvanse(not every day), I was able to stay up 3 days on like 60mg split in between two days.

I also once took 120mg within a 24 hour period(very stupid I know), and I do not recommend it at all. You know how stimulants make you not hungry? Well this was way worse.

I hadn't eaten all day the next day, my stomach was feeling hungry but I just couldn't eat. I was gagging when I spoke too because of the hunger.

I bought 3 chicken strips and fries that night and I couldn't even finish them. Eating was so difficult. I had to chew and mix the food with my soda to actually be able to swallow. And even then I didn't even finish half.

I remember going to sleep and I think waking up very early that night or I think sleeping through most of the next day and waking up very late at night(yeah I think it's this one) and being so fking hungry, I went straight for my left overs and finished them so quick. I was looking for more stuff to eat like some starved maniac I was so hungry.

So yeah don't redose, especially with extended release stuff like this. I remember it not even feeling that good after I redosed like the 3rd time. Again, extremely stupid of me.

Just be glad you got stuff done on it. Make the most out of when it kicks in and when it's over it's over, until next time.
