Definitely sounds like panic attacks to me. I was having them for awhile too. I went to the doctor and they gave me some meds to help out. I guess they say one of the possible hazards with taking E is it can lead to all types of psychological disorders like anxiety, panic attack, even obsesive complusive disorder. I was having panic attacks before I started taking E, and since I've taken it, it has seemed to reverse it. E affects everyone differently but if it keeps up and you can't seem to deal with it anymore, I would go back to the doctor and get some meds. Oh...the other thing is...there are a handfull of meds out there that won't mix with E so if youre still into E....try getting Paxil for your panic attacks. At least that way you can still roll. Otherwise some of the other meds create some pretty bad health problems when mixed with E.
