i’ve been on 40mg of vyvanse for a couple months now and i take occasional breaks especially on slower days. i’ve noticed that once i start to “crash” i get an odd tingling sensation in my head that sort of feels like when you get really intense goosebumps that make the hairs on your arm stand up? but all over my brain and when i itch my head nothing happens. it lasts for about 5 seconds then goes away for a couple but then comes back. this happens for about 30 minutes, then there are random, less intense versions of it the rest of the night. i’m not sure if this is relevant, but when i smoke on days i take my vyvanse i get the same sensation, and i no longer get high the way i used to, just numb and tired. i wanted to see if anyone else has experienced something similar because it kind of concerns me that it’s only happening to my brain and im worried that the the combination is destroying my dopamine receptors or something really important and thats why im feeling this weird shit.
