So I am only 75 kg but u have a few health concerns which make my body at further risk by being over weight. My dr prescribed me duromine to help me lose weight as I am currently unable to go to the gym due to a back injury. 

I started off on 15mg and was on it a week and nothing much really happened - only side effects were exhaustion and dry mouth. I am half way through my second week on 30mg and again not many symptoms just exhaustion in the evening and dry mouth. I guess I am lucky in that sense but I haven't really seen any chance in my body or my measurements. I am starting to walk 3km's at least 3 times a week n eating allot healthier but I am still hungry and find myself eating at dinner time a proper meal (chicken and mash). 

How long should I expect to see some results ? And does anyone know why some people experience dramatic weight shifts and others nothing? I take medications but I have never taken drugs and I don't drink alcohol so I wouldn't think I would b resistant to it. 

any suggestions ? 

I have 16 weeks to lose weight for my wedding dress as the lady I bought it off figured I could lose the weight w a stuffed up back :(
