I've been taking 7 drops of clonazepam for 5 months to help me sleep. what long term side effects to expect? is it too long a term?

Talk to your doctor: If I am not mistaken 7 drops would constitute about 0.7 mg. Having said that, I am thinking that over time you may experience tolerance and also disruption of sleep architecture. Tolerance is where the same dose does not work as well. In addition, a longer acting benzodiazepine like Clonazepam will reduce both rem sleep and restful delta wave sleep. Talk to your prescribing doctor!
