Hi there. Well only your doctor can say whether the dosage needs increasing - say from 1mg to 5mg, or whatever. The thing is, a week's nowhere long enough for them to take proper effect, but it sounds to me as though your doctor was being cautious - hence just giving you so few, and with saying not to take them every night. I know it might seem silly to you, but before you embark on further or stronger tablets, have you tried relaxation methods of getting to sleep? Stress can play havoc with sleeping patterns, but that's why sleeping tablets should never be taken lightly - because most can become addictive. You could try the herbal sort that you can buy from most chemists.
