Hey Jammer and welcome to Bluelight! Now, I'm going to run-down with you some of the basics regarding how to make an effective and appropriate post here in Basic Drug Discussion. First of all, we try to be as "scientific" as possible in our approach here and respond to issues with raw facts with anecdotal experience peppered in. So when someone asks a question like "What's your experience with these 3 drugs", there are a lot of issues already. First off, you've mentioned 3 drugs from 3 completely different classes of psychoactive substances. It is nearly impossible to describe something as esoteric as an experience with drugs to somebody else. It becomes even more difficult when you're describing a combination of several different drugs.
The thing is, if you ask someone what their experience is with a given drug, you're going to get different answers from different people. There is no answer, only opinions. You cannot make potentially deadly decisions in your life based upon opinion.
Now, regarding the broadness of your question in general. How do these drugs make you feel? It's too much potential information for anyone to give effectively, in addition to the other issues with this question I've already mentioned.
If you have specific questions like, say, "Does Lisdexamphetamine (Vyvanse), typically increase heart rate? Does it typically reduce appetite? Is it normal for me to become nauseous when taking Oxycodone (Percocet/Oxycontin)?" These are all questions with a more or less definitive answer. If everyone were to truly pour their heart into answering your question the way it is written, you would end up with pages upon pages of indecipherable and unhelpful gibberish.
So, if you would like to either create a new thread or edit the existing one with some more specificity, we'll jump in and try to help you out.
What are your primary concerns? Health? Addiction/Dependence? Effect on psychology? Dietary Restrictions? Dangerous Dosages and/or Combinations?
