Oh yeah mirtazapine is evil about making you hungry. Also for me 60mg weren't sedative at all, the 5ht2c antagonism overshadows the powerful sedation from lower dosages. I found 15mg to be much more sedating than higher dosages and tolerance developed rapidly, after just one 60mg dosage each and all sedation was gone and the med turned into a pure hunger inducing substance.
Nicotine's pretty nice but not alone, I find cigarettes to be better (and more dirty, of course) than pure nicotine, they contain harmaline alkaloids which are MAO inhibitors.. I want to prepare some e-juice with either a tobacco extract or nicotine + harmaline. But here in MX it's difficult to import stuff, thanks to the US..
Sleep is indeed a problem with amphetamines, I found meth (which is prescribed for heavy cases in the US, dosage 5mg) to be very nice but I couldn't sleep at all first.. with time this solves as the body takes the sleep it needs. If you can't sleep, clonidine can be helpful, it antagonizes the norepinephrine part and thus allows sleep. Or pramipexole, a dopamine agonist, weirdly makes me very sleepy.
