I had valium when in hospital but only 2mg and i was out of it for the whole afternoon then woke up for a little food and then thebrest of the night? So i kind of had the same effect when i first went on it... Though the difference is that ive been on it constantly since then and only now am i starting to come off.. It is so addictive so be careful with it.. I know after a few tomes taking it my body almost needed it or else id get a headache and go all light-headed! I hope this helps but i took it for a different reason! Haha
