1. Take a break. I know you're anxious for that awesome feeling, but patience is a virtue and will save some brain for you. You need to wait at least 3 weeks.
2. Why are you trying to roll when sitting in front of your computer (I'm assuming by yourself)? MDMA is an empathetic drug, you need people to connect with while on it. I've only done it once in a setting with no one around and had a friend visit for a bit around the time I was peaking. Quality roll from previous experience, but still you get so much more out of it when you have someone to share this with. I'd recommend a good friend or significant other. It still could be and MDxx pill without MDMA. If one of your friends has a kit, test it. If you trust your dealer, ask to see test results.
