We have an ongoing discussion on here about benzodiazepenes, the drugs CLKD refers to as the ones she uses 'as and when' she needs them. Without wishing to inflame the whole debate again, I just want to point out that diazepam (same as Valium), lorazepam (which is the next step up and the one CLKD is referring to) and all the others in this family, are highly addictive and can be absolute hell to come off.
CLKD is pretty unusual in that she manages to just take them occasionally - I don't know if this is a reflection of her basic personality, or the nature of her anxiety. Personally my anxiety is so relentless I've not been able to just take diazepam 'as and when' - the problem with these drugs is that when you get the amazing feeling of that horrible anxiety just melting away you want it again and again, but unfortunately you quickly build up a tolerance and become dependent and then they have no effect, but you have to keep taking them to avoid even worse withdrawal symptoms.
I'm currently stuck on 14mg diazepam every morning - it does nothing for my anxiety but I have to take it, and I feel like a drug addict. There seem to be no other anti-anxiety drugs I can tolerate, which is why I've ended up in this position. I'm ot saying don't take them, I just want to put an alternative view across because for many people this particular class of drug can be really harmful.
