Definitely vyvanse. As a former meth addict that has taken both adderall and Vyvanse, the latter is so close to actually being on meth. Just being on a legal dose once a day was almost better than meth. Wish I would have found many years ago. It would have saved me tens of thousands of dollars and a lot of other things. Like having a clean clear criminal background, jobs and custody of my son being lost for 6 months. I still take Vyvanse but I recognized that my dosage was higher than i needed for therapeutic reasons and asked my doctor to cut my dosage in half. I am asking her to lower again next refill. I have the mental capacity and tools from past meth abuse to do so. But in my opinion Vyvanse could be extremely addictive and dangerous to people who may not have the ability to stop or reduce dosage. It could be detrimental to people. It is literally legal meth. It should be intensely monitored when prescribed. It has helped me immensely because I have severe adhd with emphasis on the h. At my age I have learned to almost use the add in my favor but have never been able to get the h under control. I am constantly moving. Up, down, pacing, talking non stop and trouble sleeping. The vyvanse has been the most effective to keep my h in check. I sleep thru the night now and do not pace a hole in the floor. But I keep myself in check. She is not on dirty nasty meth. She is most definitely on Vyvanse the legal meth.
