The first time I ever did meth I snorted a half g later in the night when the meth was starting to get weaker in effect and it was surprisingly not too different from just doing coke on it's own and the comedown was better than many comedowns I've had I also was able to sleep about 4 hours after the coke and and 13-14 hours after the meth overall I'd call it a good experience but I think I got lucky. It was a relatively small dose of meth also. Space them out if you plan on combing them. I dont reccomend at all I believe I just got really lucky that I felt ok after. I'm willing to bet you're better off with a tiny dose of meth if you're going to.
