"prescribed 20 mg x 2.  been on it for 2 months now and i&#039;m weighing the pro&#039;s and cons.  i fell back to one 20 mg. per morning.  2 20 mg was too much.  granted it helps with focus, memory, and makes me a bit outgoing.  but at the price of loss of appetite, weak erection, dry mouth, headaches, weakness and muscle cramps, sweating, and a few other nagging issues.  it&#039;s not the first time for me on this med, or groups.  they really are convenient for some of my issues but at a cost.  not so sure if i want my focus, thought process, restored at the cost it brings me in the other areas."
