First day on 20mg Vyvanse as a 17 year old

This stuff is great!

About an 1 hour to 2 hours after taking it, a flip switched in my head and I instantly stopped any needless chatter and focused on my work. It really felt like I entered a mental sauna and was instantly calmed and task-oriented.

I took it at around 7:50am and began to feel really calmed at around 9am.
Thankfully the night before I made myself a strict schedule to adhere to and I followed it pretty well with 14/18 tasks done and 4 left to do between now and 9pm.

something external did come up that threw me off my schedule about two hours, but it's ok.

I did feel myself becoming more talkative at around 12pm, before that I was completely silent. Still I was pretty quiet and only said things necessary for my SAT review and video recap about how I was feeling.

I've had 44g of protein thus far and 16oz of green+black tea and an additional 50+oz of water.

Side effects for me is:

Excessive bathroom use

Heart rate speeding up

mouth and throat is a little more dry

QUESTION:

Do more mg Vyvanse prolong the effects? I chose vyvanse because it was the longest acting and I'd like to extend my peak productivity time as study and ec duties is taking up a bit of my day.

but overall I was able to get started on and complete on over 7 high priority tasks I've been putting off.

I would honestly cry about how happy I feel but I don't feel emotional at all right now.

I will be getting some protein and doing workouts 3x a week starting tomorrow, May 2nd.

Again, Great Stuff!

Thanks to my psychiatrist for everything!
