15mg - No energy boost
I've been on the 15mg for 2 weeks and can't say I notice the energy boost people talk about. I am eating better and drinking 100oz of water a day but just 2lbs lost in total. My doctor doesn't want me to increase the dosage because of high blood pressure but maybe if nothing changes she will up it to 30mg. No side effects at all so this is a good sign I guess.
