I flip flopped and mixed and matched and ultimately found the same problems with both of them, but elvanse was more convenient for work. Even on 10-12 hour shifts 50 mg of elvanse could just about get me through when with dex I would have to redose 2-3 times and potentially risk a dose dropping off at an inconvenient time.I found XR to be even worse and had to switch to Dex IR 3x a day.
But yeah I hate getting nothing done off of medication and hate being extra stressed and antisocial all the time on it. It's an awful paradox.
