At first I took 10mg, and I lost 25lbs in 2 months (along with restricted diet meal). Afterward, I find my weight didn't frop down anymore, so I changed to take 15mg.
My heart has problem for a long time, and everytime after I took 15mg, my heart doesn't feel good, therefore, I stopped the pills and take the 10mg again.
However, my weight still didn't drop down anymore ( I guess my body already used to the pills), and I just took Reductil for weight keeping.
