I thought I'd mention my own experience. I have been using modafinil, adrafinil and a host of other stimulants for over a year. Two days ago I was hospitalized after mixing 150mg of modafinil with phenylpiracetam (about 60 mg) . I spent ten hours in resus with a resting heart rate of 180 to 150 and severe AF. I suddenly snapped back into a heart rate of 80 at about 4 a.m. but still don't feel 100% I will certainly be throwing away every afinil in my arsenal. Obviously this isn't everyone's experience but perhaps worth mentioning. Certainly no doctor knew what modafinil was.
Modafinil or hydrafinil? It's good to hear you are better.
