They're really useful (and occasionally enjoyable) drugs if used sparingly and occasionally (1 -2 times a month maximum really if we're to be honest). They will relax your muscles (which is why they prescribe them for back muscle spasms) but the primary effect is to significantly reduce or completely surpress psychological and / or psychosomatic anxiety, and they also have a powerful hypnotic effect. To sum the 'effect' up, its very pleasant, often being described by those with anxiety problems as being 'wrapped up in cotton wool'. They can make your legs feel like jelly and can also cause amnesia while in effect.
If used for more than 4-7 days in a row however, the sedation soon dissapears as ones tolerance to the drug starts to climb. They will continue to provide an anti - anxiety effect for 2-4 months if one was to continue taking them on consecutive days, but as ones tolerance continues to build, they have less and less of an effect, leading most to increase the dose to recapture the desirable feelings caused by the drug. Tolerance is the first and only stop off to take one final view before continued use leads to serious psychological and eventually physical dependence that requires medical treatment to address, as stopping the use of diazepam and similar drugs while dependent can lead to withdrwal symptoms ranging from severe anxiety up to tonic - clonic seizures, and in extreme cases, death.
They're great if used once in a blue moon but can you trust yourself to not like them so much you won't carry on taking them and try and resource more when they run out?
THEY ARE AS ADDICTIVE AS ALCOHOL AND HEROIN, AND MUCH MORE DIFFICULT TO DETOXIFY FROM
The choice is yours. I would advise looking at the wiki page for diazepam, benzodiazpines, and
www.benzo.org before you go any further,,,
