Thanks for the info Valkyrie; there seems to be loads of first generation anti-histamines (that all make you drowsy) available from various sources online.
Fucking GBL!!!! What can I say!?

It shows you heaven for a few months and then takes it away.
I guess the timing is all just about perfect to be honest, another big bottle would probably ruin me physically, and only make matters even worse with my neighbors. I'm so going to miss the really long music sessions though, but definitely not the neighbor hassles. I may still order a sneaky 100ml every few months or something, but certainly not too often.
As my tiny remaining amount of GBL is already accounted for I'm not really craving it at all, but am quite strongly psychologically craving the gabba b meds like baclofen and pregabalin. It doesnt feel physical in any way; no tremor, headaches, nausea, heart function issues, or any other symptom that i can think of. Giving in to the cravings only seems to make them stronger the next day has been my experience so far since quitting GBL, so I'll see if i can make it through the rest of today with no more gabba bs, or if not, leave it as long as possible.
Well there goes another substance to cross off the potential 'Physical Dependency' list.

2 down, 2 to go. Opis/Kratom and GBL quit, benzos and stims to go.
It's entirely psychological with stims, i guess i could start by gradually reducing my doses, and not taking any dose any later than mid afternoon which will then definitely not be interfering with my sleep, as i fear is the case at present.
EDIT: No I lost my job Dan, gonna start looking again now that I've got my worst and most destructive habits sorted.
