"i am on my 2nd week ( 7/10/15). first week felt horrible - morning headaches, severe dry mounth....actually gained weight. at the begining of the 2nd week - headaches gone but now have mild body aches...still wtih dry mouth but lost the initial weight plus 2 pounds!!  i do not feel hungery at all...but it took about a week for it to kick in.  the cost is prohibitive...i will not re-order. even with insurance i can not afford $200.00 out-of-pocket. it does not give you energy like phentermine....just makes you feel full.  oh, also, very constipationg!!!!!  i will finish the bottle - it is working for me. you have to be a &quot;responder&quot; to this medication and only 50% of people are ( i didn&#039;t know that) see if you can get the first 15 days free"
