sorry I cant answer your question. But can you tell me more what you mean with "difficulty breathing"? I have that too some times and I think it gets exacerbated by meth, but Im not sure its the same..
I think mine is some kinda "panic anxiety" that I got after abusing 6-apb/mdma a period.. and its exacerbated too much when smoking cannabis, to the point I stopped toking for months. However I think its gotten better tho, and while I get some "breathing problem" at random times thru the day, doesnt last long or is very strong/much of a problem.
I have noticed this has gotten worse after periods of meth again, I guess its amphetamines in general worsening such a condition?
My issue is... a bit hard to explain, but its as if I "forget" to inhale some times, or take too small breaths. End up sitting focusing on breathing, making sure each breath is right tempo/speed and all.. and it may disappear as fast as it came on, jsut suddenly I think I can "forget" it, and its gone...a while.
Also, why do you snort it? Have you tried smoking it, at all/ever?
I think I need ATLEAST 12 hours after my last dose before I can think of sleeping, and some times its taken me more than 24h since last dose.
I feel that when I have my first yawn, then I may be able to sleep..but usually not before, not without a benzo atleast.
The nausea, any idea where its coming from or you think a reaction to the drug itself? Personally I get nauseas when Ive gone on meth whole day and havent eaten anything or such, and think I get much better after I have forced down some food. Think this would help, or another type of nausea..?
Im not sure what you mean by reaching (?) "the wall" as you call it, you mean you keep dosing but youre not reaching back up to the desired place you were, and looking for ways to get around this thru different dosing/times or ROA?
Again I dont really know..sorry.. Im just some stupid newb and very new to meth myself, but Id guess ROA wont be much different in this respect, and once your body has reached a point where it cant sqeeze out more of these feelgood-juices (dopamine? no idea..) and youre just feeling bad/never better, then its probably best to rather focus on getting to sleep; stop dosing and wait until tired, to recharge the brain for another day of pleasures instead and not really much that can be done before that...
again Im just some n00b dont really know, just thought Id add my dum input anyway incase it had any use or anything. Smoking meth atm myself
Sorry let me know if this was just in the way or anything and Ill delete (if possible) :/
anyway, good luck.. be careful and take care, stay on the ssafe side- eat somehing healthy and go to bed!
