There's caffeine tablets you can get (NoDoz or something) which you could consider but I've not seen them here - which is curious and might indicate they're banned. You'd need to confirm that from a more reputable source than a forum post.
well unless nodoz is mixed with something else, i doubt it would be banned, else every coffee drinker in the country would be in jail - also bear in mind that arabic coffee is one of the most potent coffees of all!
