"i took 2.5 mg. for about a week and it helped incredibly. then i began taking 5 mg. and after a few weeks i realized that it didn&#039;t help as much as the 2.5 mg. that i took before so i went back to taking only 2.5 mg. and it really helps. if it doesn&#039;t help you need to try taking different amounts and see what works for you."
