No stimulant seems to be strong enough/last long enough.
I've tried just about every ADHD medication there is, both stimulant and non stimulant. (I'm also on 20mg lexapro and 300mg wellbutrin). Even when started stimulants, they didn't seem to last long enough or be strong enough. My doctor let me work my way up on the dose. I've done this routine with every stimulant up to the max dose, but even the max dose has never been enough. Currently, I'm on 20mg of Dyanavel 20mg of Evekeo. I've tried the max dose of almost every other extended release stimulant along with 20mg of either evekeo, adderall, dexedrine, or zenzedi. I've also tried the max dose of every instant release stimulant I just mentioned, plus some others. I've also tried taking tums with it, avoiding anything acidic, combining with caffeine, vitamins and supplements like magnesium, B6, or L-Tyrosine, and taking tolerance breaks. At one point I went almost 2 years without any stimulant. Recently I took 3 weeks off, and then continued with the 20mg Dyanavel, but also tried taking 20mg Evekeo 3-4 times throughout the day afterwards. Even 20mg Dyanavel paired with up to 80mg Evekeo (yes 80mg) AND 300-400mg of caffeine spread throughout the day, it still had very little effect and for a very short duration. I've never noticed much difference if any in my appetite, sleep, heart rate, or blood pressure. Why is it that no matter which formulation, combination, protocol, or dose i try, nothing lasts long enough.
