I took Edronax for about 2 years before it "bombed", i.e., it stopped working. The smell of it, bleugh.
I took it for depression and to supplement the dexamphetamine I was taking for ADHD. It had a very mild effect on my ADHD when I didn't take dex for a day or so. I didn't experience any side effects, not even weight loss (bummer).
I didn't experience rapid heart beats and my blood pressure was fine every time I went to the doctor.
If you're going to take Edronax, I hope it works out for you.
