Very informative, thank you. Handy for me was the info about side effects. It is good that everything is assembled in one place.
Everything is simple and straightforward. But I was surprised that you can take pills before breakfast. Isn’t it strange? Is it possible to take medication on an empty stomach?
WoW! So many precautions before using it. Suggests the doubt… Probably I should be more serious and talk to my doctor…
I find it so annoying I should tell everyone I take Duromine, even a dentist. I get the importance, but still. It annoys me a lot. Who can relate?
Oops .. And I shared my medication once. Well, that person had the prescription earlier, and I just gave her my pills cause I didn’t need them. Not a big deal. I don’t see any reason why I wasn’t right.
I can’t exercise while I take Duromine. The article advises calling a doctor. My doc said it’s OK. Should I change a doctor then?))
Omg omg just saw that “serious side effects.” That little pill can really do that?! Shocked
