Thanx for all your support guys. But after almost two weeks I've made the decision to quit dexamphetamine. Even in higher doses it has more negative than positive effects for me personally. To sum it up, I allways feel like I'm on drugs and sedatet, and I can't stand that feeling. Even my spelling gets worse, I have to check every post for typos over and over again, that can't be good. Since DL-Amphetamine worked quite well for me, I'll go back to that, and then check if I may have a sleeping disorder, and if there's a med for this condition that works better for me.
You guys be well and take care!
