I recall back in the 80's, a friend rang me up from the loony bin where he'd been sectioned...
"How are you?"
"Um... not so good..." (an understatement, I was suffering from deep depression, panic attacks and exhaustion) "A bit 'doen'.... y'know?"
"Oh dear - I'll have a whip round. Be out in a couple of days, see you then!"
Sure enough he wwas, and handed me a Tesco's bag full of bottles of multi coloured pils. Later on I borrowed a copy of Mimms and checked them out. Mostly ghastly Thorazine style major tranks... ugh!.... a few bottles of things to deal with SFX of previous.... yuk!... but one big bottle of Ativan, filled with yellow and blue pills. Hurrah! Alas for me, I foolishly assumed they followed the 'Valium code', i.e., the blue ones were strong, ane yellow ones half strength, So I had a much needed, restful week taking the yellow ones... then, luckily for me *before* I used up all the yellows, I thought 'I deserve a treat!' (as you do), and took a blue one.... fuck all. Maybe a duffer? Took another.... sod all! Ulp! Checked the book... oh shit, the blues were not just half strength, they were a fifth strnghth! Disaster!
Sensibly (for once), I thought 'must knock this on the head.... NOW!' and did just that.... awake all night, fortunately for me I hadn't gone TOO far, and was okay a day or two later. A close run thing though - they were later withdrawn, *dangerously depence forming* apparently.
