I lost a load of weight when i was younger on Duromine (maybe 10kg - but then wasnt really that heavy and probably should not have been prescribed it)
I again when back on it when i tried to loose weight for my wedding and failed, this time i did it more sensibly and lost the weight slower and concentrated on changing my habits too (it can be a vicious cyscle, of going off and on again)

This is a fantastic drug for rapid weight loss, but you have to be very careful that it does not all go back on and you dont get additcted.

My tips... (from personal experience and also nursing)
* like Lisa says, take it really early in the morning - like set and alarm for early and take it.
* Eat breakfast before or with the tablet - you must have breakfast otherwise you will not feel like it later.
* Make yourself eat small meals through the day - you will not feel like it at all, but you really should for your health.
* be honest with your family and friends about taking it... it is a speed derivative and some of the side effects are not pleasant (not going there as you asked) and it is better for people around you to understand why you have changed.
* try and stick on the same dose for longer than you want to... you body will get use to it and then you will find that the eating old habits come back or the drug is not as effective, work through this instead of jumping to get the higher dose straight away - make sure you start on the lowest dose, i think it s 15mg from memeory.
* try and avoid taking sleepng tablets to help you sleep - the insomnia will settle down as you body gets use to the 'speedy' feeling....
* when you reach the 20kg - STOP, it is so tempting to stay on them and loose a bit more, but try and resist that feeling...

If you dont eat much at all, you will force your body into starvation mode, that will slow you metabolism... this will mean that the weight goes back quicker when you stop taking it (regardless of your food choices). Make sure that you eat something every 4-5 hours - you really wont feel like it, but in the long run it is better to force even an apple or a box of saltanas in.

Be careful with the water... the first week or so you will be increadibly thirst, make sure that you dont drink too much as you will unbalance your electrolytes and make yourself very unwell.

The honesty thing is important as you will seem like Supermum - all the jobs will be done, your house will sparkle and there will still be time to sit (but you probably wont feel like it to begin with, sitting that is) - when you stop taking them this also will change as you will have less energy.

Oh and when you stop taking them, do so slowly - gradually reduce the dose (if you get to the 45mg tablets go back to the 30's then the 15's) and then take one every second day, this way you are less likely to put weight back on, as you will be mindful of what you are eating.

I hope this hasnt been too negative, i didnt write with that aim, more just tips... Duromine does work and i am sure that you will lose the weight that you want

feel free to PM me if you want any other info (positive or negative)

Goodluck
