Hi junko. We don't use "SWIM" or "my cat" or anything like that here at bluelight (it's actually in the bluelight user agreement), because anyone that reads your post is going to know you're referring to yourself. We find these terms to be futile in trying to avoid self-incrimination.
But to answer your question, meth isn't a very maintainable way to diet, and if your only 140 lbs, you really shouldn't be using it to lose weight anyway as you will lose way to much. Also, when you stop using, you'll probably gain all of the weight back, plus some. The only way that it could help at all is if you use it todrastically change your eating habits, but you'll still probably gain much of the weight back.
However, if you insist on doing this, really you should try dosing about 50...maybe 100mg from each batch to gauge how potent it is as meth is always hit or miss in purity/how stomped on it is and the quality at which it was synthesized. Taking meth orally will probably last you at least 8 hours if not 12, so be sure to keep this in mind when you dose if you're trying to avoid staying awake multiple days in a row. It's really easy to accidentally stay up for 3 days when doing meth, because you get into this awful cycle of not coming down soon enough to get some sleep before you start the next day, so you redose, and then end up having to redose again to finish up the day, and winding up back in the same place. Not to mention how easy it is to get in the habit of redosing to avoid the really shitty feeling of coming down.
Sorry to preach, but trying to let you know what you're getting yourself into.
Good luck with your dieting, regardless how you do it and welcome to bluelight.
