hi ive just started using this medication on tuesday for insomnia..the doseage is 15mg. on tuesday night it knocked me (had restless legs poss a side effect?) out for apart from going to the toilet 3 times but managed to go straight back to sleep, felt crappy yesterday tho very tired but not enough to sleep again. took another tablet last night and only got a few hours sleep last night as it took well over an hour to work? also taking prozac too....should it be making me really sleepy straight away and make me sleep all through the night?
