Hi folks, appreciate the responses and info. I could have added some other info and been clearer. I had 2g at the tail end of last year and as it did what I was after thought I'd just make a small bulk purchase of 10g about Feb this year. Finished that in Sep but after a weeks holiday of overindulgence generally decided on a break. On reflection I did overdo it a bit at times, but nothing too much. Used it for a boost out socialising as it goes well with alcohol and I like to smoke when having a drink and the drink/eph/marlboro package was pretty good usually. Also used it for a pick me up at times, for focus when writing some lengthy work reports that would otherwise have been dull and also, you may laugh when fishing during the night. I had some MPA also from same place but did not really get on with it and much preferred the Eph. I was just surprised at the different crystal format compared to the powder. However Ive tried a bit more tonight which has felt better. Ive had a dragging cold over the last couple of weeks, which I think may not have helped my initial try with crystal. I think the combination of cold, attempts to smoke and ephs knack of snotting up your ears, nose etc probably left me feeling worse physically but stimulated, anxious and let down. From my experience the powder is good and I'd be happy to have it again. As others have mentioned at times it can get a bit claggy and you can feel it on your chest at times. I'll update when given it more time. I'd agree that it can bring anxiety. Ive been out on a couple of occasions having a good time and been the last of my bunch out, perhaps wanting a bit more from the night as opposed to my non stimmed pals. Once I started to feel that everyone was looking at me and something bad was going to happen. The second was when I was outside having about 3 cigs one after the other due to the eph and there was a kick off with some people and bouncers very near me, which was nasty and ended up with ambulances called. Normally I'd deal with stuff like that no problem and get on with my day, but I was in a taxi very quickly. My perfect mood switched instantly to total edginess and anxiety. I am going on now, so its obviously working quite well. Cheers folks
