Redosing mdma 5 hours past the initial dose is going to be pointless. Heh, I would know.
I'm sure you'll be fine. The fact that you're here afterwards while posting on BL is already a good sign. If anything, seeing a doc or going to the hospital will help you a lot better than anything you can get from here (besides important info and safety precautions).
MDMA is very potent material! I've learned that lesson many years ago and don't mess around with reckless dosing anymore. I've said it before, but the only negative effects I've ever gotten were an inability to eat or sleep properly, but the dichotomy is that those two habits are very important for our health. I proceeded to get wrecked from it, but a couple of years of not touching it with a 10ft pole did wonders, and now I love good food and good sleep.
Shout outs to roast beef from The Hat, a bag of jalapeño kettle chips and an Orange Bang!!
Edit: Forgot to kindly add that you should read the forum rules before posting. No SWIMming here! Those are for pools/beaches.
Also, this forum is unusually getting swamped with the same/similar type of threads popping up multiple times. I'll be doing some house work here tonight and cleaning up a little bit of the mess. The search function is your friend.
