Great advice I was given by someone whose been on almost every ADHD medication over the last 30ish years is that because it does effect everyone different you may have to do a bit of trial and error with which one works for you. She said you would know in 2 weeks if it was working for you or not, or if you needed to increase your dose. I am 33 years old, and was just diagnosed with combined ADHD, and neurodivergent in May. I started on Vyvanse, and knowing in two weeks rang true for me. It started working immediately, and amazingly, but by the end of 2 weeks I'd started feeling like I did before I started meds, so I increase my dose, and it's been working great ever since. Other advice I'd give:
:The medication does not last all day. Expect it to wear off around supper time. Everybody metabolizes it at different rates. Mine wears off after 11 hours.
:I literally crashed when the meds would wear off the first 3-5 days of taking meds. Because my body was SO starved of all the stuff the medication gives it threw my body right out of whack finally having it regulated. I haven't had any issues with crashing since, not even when I upped my dose. Be aware that this can happen.
: Journal it! In almost everything I do I can tell you I like it or I don't, it works, or it doesn't, but I can not for the life of me tell you why. If you wind up having to go through the trial and error process through all the brands and their generics(the generics are cheaper, but WILL make you feel different than the brand), you don't want to go to your Dr and say I don't like it, or it doesn't work, and not be able to tell them why. Doing this actually helped me pinpoint when to take my ADHD meds in correlation to my other morning meds to give me the most energy, and least amount of symptoms in a day. You don't have to read your transcripts to your Dr, but read it the day before/of your appointment to familiarize yourself with the why, and then if your Dr does ask you something specific you can pull it up and look. I used to just use the note app in my phone but switched to the Daylio app. I love it! It has writing templates for your notes, And you can customize your own. This is the template I customized for myself with starting ADHD meds:
May __, 10mg Vyvanse:
Taken __:__am, other morning med taken __:__am, B12 __:__am, ___oz coffee started at __:__am, ___oz water throughout Day
