That does happen... long time use of E makes your body go through that, but also it could be the pill was laced with K.

i abused ecstasy for 3 years
Im trying to give up. i get the same feelings you do also electric type shocks behind my eyes when i move my head side to side.
the feelings will start to go away after a couple of weeks and your emotions will go up and down.

The part about the strange feelings when you try to go sleep sounds like sleep depravation, get some 5-HTP as this stuff not only will give you good long REM sleeps it will also build up your seretonin levels which the mdma have depleted.

Firstly, have a break for awhile. By all means you can take pills Just every now and again. A month is a good time to wait.
Also pills use up seritonin and dopamine. Eat pleanty of fruit and chocolatte on comedowns. And there are suplements that help like 5-htp (I think). They can be brought from health stores.
As for dxm, ket and other disocatives. I can only relate my experience with nutmeg, strange experience to say the least (took to much, almost died...stupid me). Any way I contined feeling side effect for a few weeks. Kinda like feeling out of it after a big smoke.
If you want my humble opinion mate, take a break for a few months and things should clear up. And definatly take mounth breaks between rolling.
Oh yeah and 7 pills in one night isnt that much, i know someone who has done 21. 7 is a normal amount where I come from.

What you are describing more closely resembles the aftereffects of dissociative use than an MDMA "hangover". Ecstasy pills are often cut, and DXM is one of the most common cuts. It's possible that you got some pills cut with ketamine or PCP (also dissociatives), but DXM is far cheaper and more easily obtained.

I have suffered similar side effects for about a week or two after a large dose of DXM alone on more than one occasion.

All of this aside, weekly ecstasy use is extremely hard on your brain, and you should stop now before you do more damage than you already have. Alexander Shulgin, the chemist that rediscovered the recipe for MDMA in the 80's, has said that he believes that MDMA use is only relatively safe if you keep it at about 4 times a year or less.

i feel very upset and angry the week after i do it. my jaw too clenches harder when i yawn than it use to. i get alot of headaches too.

i had a pill with k and it made me so mad about everything i couldnt stand to be on the dancefloof
i had to stick to the carpet. i couldnt handle anyone touching me either!!

but after all this id still do it lol but thats just me

I also used ecstacy for about a year and a half, sometimes taking up to 7 tablets in one night. I started to get headaches and muscle spasms in my neck and back. Further symptoms of insomnia developed. It felt like I couldn't shutdown my brain to fall asleep. Sometimes I got strange feelings in my arms and hand as if there were ice flowing through my vains. Had to start taking strong sleeping tablets. Symptoms would gradually vade untill I did E again.The symptoms would then return. Definite connection!! Also found that after yawning my teeth and jaw seemed to clench just that little bit more with a strange sensation. This drug might affect different people in many different ways. Please stay away from this stuff!! I wish that I never tried it!!

I never experienced that but I assume its perfectly normal. Long time use of ecstasy can affect you in many ways. What I have experienced is that every so often I get extremely depressed for absolutely no reason it lasts about a day and then goes away. I learned that this was a side effect of ecstasy use.

I wish I never bothered with e too, only done it once, dropped 4 pills at the same time, schoolboy error

YEAH MAN I'VE BEEN POPPIN X FOR LIKE 3 YEARS...ITS LIKE THIS MAN YOUR BRAIN LOW ON DOPEAMINE AND STREOTION...SRRY IF I MISSED SPELLED ONE OF THE CHEMICALS
