This thread is pretty old now but I thought I'd share my experience with Vyvanse since I came here originally to know what to expect before I took it and I feel that my experience could be beneficial to others thinking about taking it.
I had read to take it in the morning but I stupidly waited until almost 2 in the afternoon. I had no real reason of taking it other than I had the day off, could use a mood life and I had heard it provided that much.
I popped a 50mg pill at 1:55 and decided to go for a walk to a spot by the river with a book. I checked the time about an hour after taking it and couldn't feel or notice any definite affects. As time went on I DEFINITELY felt a mood boost and I was feeling great. I laid on the grass reading a book for over six and a half hours and was completely engrossed by it. I definitely felt the focusing effect Vyvanse is supposed to provide, though occasionally I would glance at my phone and end up browsing for 20 minutes. I feel that my focus could easily be shifted and this could be problematic if I were using the drug
to study or something.
The initial effects of the drug were great. I wouldn't say it was a "high" but I felt awesome and was extremely happy and really really calm. I have taken adderall
in the past and I found the two experiences to be completely different. Adderall makes me feel like I could run 10,000 miles, where I was perfectly happy to lay down all day on Vyvanse.
However, when I eventually got up I started to notice negative effects. The first thing I noticed was a loud buzzing in my ears, which I thought at first might be construction in the area. But nope, the sound was coming from inside my own head. It soon receded to a silence and I felt for a moment that I had gone deaf because my hearing was so altered. It was the strangest sensation and rather unpleasant. It was as though I was hearing everything, yet nothing at the same time. So sound was the first side effect
While I was walking home, I noticed the second negative side effect. My jaw felt extremely painful, as though I had been clenching it all day. Not only that, my tounge also hurt extremely bad as though I had been biting the sides of it. I couldn't stop clenching my jaw and it was almost like a tic.
When I got home it was about 8 pm. I laid around until about 2 am, when I realized I should probably go to bed, even though I was WIDE awake. I ended up laying in bed miserable (still clenching my jaw) until 8am when I dosed off until about 10:30. I felt the effects of Vyvanse from about 2pm until well after 8am the next day. I had to work that day at 4pm and was running on 2 1/2 hours of sleep. I would suggest not taking this drug unless you want to intentionally pull an all-nighter, or you have a good two day window of nothing to do.
Another side effect that is bad or good, depending on how you look at it, was that I had no appetite whatsoever and I did not eat at all the day I took it. Furthermore, the sores on my tongue from biting it all day stopped me from eating for about the next two days as well. So I guess Vyvanse would be beneficial to someone who wants to stop eating? I DO NOT RECOMMEND THIS.
It took me about 4 solid days to recover from my day of Vyvanse. I felt incredibly shitty the next day and I was still in a haze the days after that. In about four days I finally felt normal again. The sores on my tongue were probably the worst side effect as I had white lines running down both sides of my tongue from biting it when I clenched my jaw.
I'm telling you straight up, I will probably never take Vyvanse again. It was awesome for about 6 hours but the negative side effects
were way worse than the positives. I would not recommend this drug to anyone who thinks it will get them high because it wont. It will make you happy, calm, and focused for about 6 hours, then prevent you from sleeping and eating, may alter your hearing and give you a nervous tic.
