The recommended starting dose is 0,5 mg. You stay on this for a week and then up by 0,5 per comming week until you you feel effect. Stay there and up if you want to check effect of higher dose. Everyone seems to have their sweet spot for best effect. Usually do not go higher than 4,5mg. I have been experimenting a long time with the sublingual drops. Hoped they wouldn't upset my stomach, but they did and really didn't find any real effect.Hope you have better luck.
