Normally one should never try to combine two drugs, especially two as powerful as acid and E. Candyflipping doesn't just refer to the combination of the two; it refer to using them in a staggered method that produces an entirely unique effect that is unlike either of the drugs by themselves. So first of all, never take acid and E at the same time, or even within an hour or two of each other! This will produce a sort of drunken intoxication which you might find fun (or you might find unpleasant, like me), but in either case it does not qualify as candyflipping.
Candyflipping requires that the relative "peak" times of the two drugs (from the 1hr mark to the 3hr mark with E, and from the 1hr mark to the 4h mark with acid) do not overlap. You can theoretically do it in either order, but I (and friends of mine) have always done it with acid first, E later. The most important thing to know, that I have deduced by careful (and sometimes unpleasant) experimentation:
Take your E exactly four (4) hours after taking your acid!
Why is this so important?
Well, if you take your E early (like say, after 3 hours) your acid peak won't be done yet, and the drugs end up sort of fighting for control of your brain. This is not a very fun sensation; you end up feeling lethargic and sort of light-headed. You may come out of it after an hour or two, but you will have missed the "candyflip" and will be just left feeling like you took a lot of drugs, and sometimes slightly spacey depending on the person. (Editor's Note: Not everyone agrees about this; one person sent a comment saying that they don't get much effect doing it this way, but they have a "brilliant" time when they take a low dose of MDMA about 45 minutes before ingesting LSD.)
If you take the E late (say, after 5 hours) you'll get a similar effect as taking your E too early, but probably not as strong. After 45 minutes or so it will clear up and you'll find that you're just rolling from the E, and it's not much like you took two drugs at all, more that you just took one after the other.
Another important thing is dosage. Taking less acid causes it to come on more slowly, and as a result taking your E at the four hour mark may actually be too early. Taking a lot of acid works great as long as you can handle it but in this case you may want to take your E slightly earlier, say at T+3:45. Generally I just recommend a normal dose, 3 hits of standard blotter paper, but again there's nothing wrong with more as long as you can handle it.
With E, you probably want to take a minimal dosage, or else it will just overpower the acid and you'll be rolling (not a bad thing, but you'll miss out on the candyflip). If you have a batch of pills and you normally take 1.5 pills to roll, then probably try either 1.5 or 1 pill. In a nutshell, it's better to err slightly on the side of a low dose than on the side of high.
You've only dropped acid twice, I think you should trip at least 5 times on acid. With candyflipping things get a intense, it is the most beautiful thing ever, but the experience is pretty hard/intense. Get more comfortable with acid first...
