I took 0.037mg (a quarter of a 0.15mg tab) in the morning during the first weeks and it made me focus quite well and gave me lots of energy. Then the effects faded a bit and now I take it in the morning and after lunch if I have something to do. If not, I take another 0.037mg just before going to sleep, and it also makes me sleep well. What's going on? Is this forever? Is this a miracle drug or will I find my self increasing the dosage after a few weeks or months?

Edit: I was originally prescribed it for peripheral hyperadrenergic symptoms in the context of elevated urinary metanephrine after ruling out feochromocitoma with a chest CT. Didn't expect to have such great mental effects....or maybe were those peripheral symptoms fucking me up and this is what being normal feels like? Never thought I might have ADHD
