Hello never. happy: At the top of your screen, in black lettering, you should see where it says: "Forums". If you hover your cursor over that word. the first thing you'll see in the "drop down" is the word: "Index". If you click on that it will take you to a listing of all of the forums here on PC. Each forum listing also includes a description of the purpose of the forum. You can go down the list, find the forum you think is the one that is most appropriate for your topic, click on that forum listing, & it will take you there.
As for your question, whether or not it is okay for you to start taking Provigil is really a question for a medical professional. No one here on PC is in a position to make recommendations regarding the appropriateness of taking, or not taking, a certain medication. Members may offer you their experiences with a particular medication, if they've been on it. But as to whether or not it is appropriate for you, this is a question for your doctor or other medical professional.
