I took mdma last night, 400mg and im 16 weighing at 114. Later in the night i also took some xanax, some muscle relaxer, a bit of riddalin, and i think a little sleeping pill. I went to sleep at 6:00am and woke up at 8am feeling a lot of anxiety. I have a terrible headache and think i caught a cold as well. Will this go away im in a lot of pain and its now 11:18pm and i still cant sleep.
