Depends what you're looking to get out of it. Moderate dose eth (@30-50mg) is all round good, makes you more alert, functional, in a better mood, more outgoing. There doesnt seem to be any point going any higher than that as you just increase the bad side effects - jitteryness, palps, stomach irritation etc. I usually have 2 or 3 such doses of eth every day, so 1g will last me quite a while.
I just simply could not have a gram of pv sitting around if i had any spare time, I dont even buy it by the gram anymore, its too much, makes the sessions too long, as the only way i can end them is by either consuming the whole lot or flushing it. Ive usually had enough after 1 or 2 sessions now, (possibly use about 100 - 150 mg per session) and then flush the rest.
I hate to be wasteful, but like i say i cant have pv lying around, or its just gonna get vaped first chance i get.
PV could be a functional drug if you are extremely self disciplined, and keep doses low and spread far apart. Its extremely easy to over do it, youve had it then in a functional sense, you can just get 'locked into' one activity for 30 hours or something. Its difficult just to take a break and have a piss. For myself, nothing good comes from the stuff. Except maybe not eating the 6000 or so calories i would have eaten otherwise. Makes my fluctuating mini pot belly virtually disappear for a day or 2, simply because theres nothing in my stomach.
