I have been using the 30mg tablets for almost 2 weeks now. Week 1 was super, and i loved the feeling of not being hungry all the time. I have been70kg to loose, last week i lost about 5 kg which is the most i have managed to loose in 10 years. I have bipolar mood disorder and the meds really make me hungry and sluggish at the same time. The duramine made such a difference last week i feel so disappointed now this week cause i have been getting hungry again. Is this normal?
