"my dr gave me two sample packs and told me to take all the 10mg tablets and once i was done i could go up to 20mg if i needed it, but i continue to get a prescription for 20mg and cut them in half so it lasts me twice as long. she told me i would have upset stomach the first night and that was literally the only bad side effect i had! i take it after dinner/before bed. right away it made me feel more awake, able to handle things my stressors better, and gave me a general sense of well being. i can still get aggravated so i don&#039;t feel like a zombie, and i&#039;m still able to have the big o. i am 36 and have tried 10 or so different antidepressants over the years since i was in my late teens and nothing has ever worked as well as this."
