Hi Eccay,
I'm glad my post is helpful for you, that's what this forum is all about. I really don't know about doing halves, I'll explain my experiences. I used to only ever take halves, I was too scared to take full ones. Looking back I realise there were quite a few times that I got all the anxiety on the come up but it never really resolved because I didn't reach a euphoric peak. the time i had half a green fish was a good example, when it came on I felt ovwhelmed with anxious energy, but because I only had a half, I didn't really reach a euphoric phase where the anxiety resolved itself because the euphoric qualities of the drug took over. Same when i had half a beige amsterdam. There was a time when I only did halves that I was at a pub with friends and they had blue barrels. I wanted one, but only a half, but i didn't really have a way of breaking it in half, so i took a full one. Wow, what a difference, had the usual come up anxiety, but it really just got to a critical point where the euphoria took over. I couldn't wipe the smile off my face, and I was totally at peace and relaxed. I find halves can put me on edge and leave me there, but a full pill of a good strength will always tip me over into the 'who really gives a fuck, I feel so good' frame of mind. The reason you are hesitant to take a full pill is 1. you don't know if you could handle it, 2. you don't want to OD. I think it would be extremely unlukely that anyone will OD on 1 pill, especially a guy, and also 1 pill is really not that much stronger on the come up, it just takes you to a totally different place, a place you can't reach on a half. If you are in a chilled out environment you would handle it, you just have to remember to have faith in yourself, and not fight the feelings. Surrender on E is such a blissful feeling, especially when the waves of euphoria start to spread over your body. I always find mdma is so much more of a body feeling than a mind feeling, maybe that's just how my body reacts, but i feel the anxiety in my body on the come up, then as the euphoria takes over, I also feel the sense of well being in my body as well. As you would know, if your body feels ecstatic, then the mind will put away all its fears and follow. You can try a half if you like, but i feel you won't really know or experience what I have described until you take the plunge and do a full one in a chilled environment. Just tell yourself you're ok through the come up and I reckon you will really enjoy the experience, I know I did, and now I don't take halves unless I have no other choice.
P.S. sorry for the long post, but it's impossible to convey the true feelings of these experiences in a few words. Hope this helps.
