Tried some methoxphenidine. Was much more pleasant that diphenidine around similar doses and easier to snort. Methoxphenidine seems to be functional, though I did suffer some speech issues.
On Wednesday I found out that my dad had died on tuesday. This shook me up fairly considerably, considering I hadn't spoken to him for 14 years, but after taking 200mg (orally) and 60 - 80mg nasally I was pretty much over it a few hours later, prompting me to assure my girlfriend that if she ever did die I wouldn't consume any drugs and would take the grief "raw". I later had to qualify the statement somewhat.
