Same ol' story as before - 20mg ritalin and 2 and a bit ml of gbl.
Last time I was enjoying it, I fucked up by re-dosing even though I had a seizure-like aura. Took precaution of increasing my epilepsy meds today and no intention of doubling up. Don't want another set of battle scars from a drug induced seizure - moral of the story, gbl/ghb + epilepsy = poor combo...
...edit...
This past experience played itself out - I had another seizure, though not of any great intensity (no scrapes). I guess this is the nail in the GBL coffin, <sigh>. Can't believe I've got to pour away the best part of a litre. I really thought that not re-dosing would be sufficient to avoid trouble.
