Ecstasy causing Anxiety when effects wear off

Hi, I am a twenty years old man. I have been taking ecstasy ever since I was seventeen. It all started on my friend's birthday party. What I felt than was indescribable. I was full of energy, and I had whole different point of view on life. After a certain time of using the ecstasy, I started feeling anxiety when the effects wore off. Now the anxiety is occurring every time the effects of ecstasy wear off. What could be the problem? Could you tell me something more about ecstasy?

Hi, I have seen a lot of young men in your situation. Ecstasy is related to amphetamine. It is used a lot. The things a person feels when taking it are pretty much the same as the experience you described. However, most of the ecstasy is produced in illegal factories. It could contain some poison's additives. These additives make you feel anxiety. You see, long term consequences of taking ecstasy are unknown but some tests prove that it is very toxic and that it damages your brain. There are a lot of cases of deep comas and deaths. I strongly recommend you to stop taking ecstasy and do it by seeing a professional therapist.

I Tried
for the first time last night around 9:30 pm. I started to feel effects around 11pm, effects lasted around 5 hours or more. Some of the effects were energy, dizziness, strong buzz like effects, euphoric feelings, happy, silly, and energy to dance all night long. The product made me horny, although that usually doesn’t take much.

I bought the product from The product came in a powder form with directions to add 1 scoop to fruit juice. I still have a lot left over for next week. For the amount I took; I think I will get around 9 servings out of one pack; although it says 20 servings on the directions.
