Hey there whocouldwinarabbit

cool name by the way!
MDMA is my all time favorite and I am sure others will agree. for my first time I had around 60mg. I'm 5ft 4 and weigh just over 8 st. I put it under my tongue

I had only smoked weed and tried a little bit of cocaine in the past. It was a beautiful experience for me and I believe I could have taken more without feeling uncomfortable. I have quite a low tolerance too.
Comming up can make you feel a little nauseated but that for me passes very quickly and very rarely happens to me with pure MDMA. Like the others have said, get yourself a test kit such as dancesafe online and make sure your taking what you mean to they don't cost much. also you should look into the dos and don'ts with MDMA. Don't get too dehydrated or drink alcohol.
I have tripped of MDMA before but it's nothing like other tripps I have had. for me MDMA trips are subtle. Just a bit more colourful and rose tinted. I see light smoke and sometimes get light swirly colours around the edges or my vision. Afterwards things seem to become slightly glittery to me until I fall asleep
I would say take half, but the final decision is up to you my friend
I hope this helps

send me a PM and let me know how it goes if you can

I love to hear about people having a good time
Have fun and be safe!
