Being hungry is a great sign! It is the bodies way of telling you that it needs fuel. Remember, to graze through the day, I always keep almonds with me just to eat when I can. Have fruit as well, it a huge benefit to your refuelling the body. Are you eating healthy? This is the hardest decision to make, and also the hardest habit to break. I convinced myself I was eating healthy, when in fact I was just kidding myself which meant I was getting nowhere fast, and feeling frustrated with the lack of results. So as long as you are really eating healthy then you are beating the inner demons at the game they know how to play. It's hard, no one ever said this was going to be easy.
Drink heaps of water as well, one thing you have to remember is this, your brain has two trigger mechanisms, 1. Hunger and 2. Thirst. Now, these two parts of the brain that that recognise these feelings are right next to each other and are central inside the old grey matter, so in fact, you may feel hunger, but in reality your body is craving water. Remember, your body has now upped itself with Duromine which is working your body just that little bit harder so it is needing to replace it with water.
Once you drink water, the brain doesn't recognise this immediately and it requires a little while for it to register that is was water it needed, not a food substance. You may drink a whole bottle of water straight up and the brain will still think it's hungry, but after 10 mins or so, that hunger will transfer into a full sensation.
With your exercise, go for a slow walk, heck, just go outside and walk up the street to the corner and back. Walk 100 meters and turn around and head back. As long as you are doing something that is out of the norm from what you did previous to starting to want to lose weight then all is okay. It seems you are focusing too much, and not allowing time to just let time take its course. Like it was suggested, baby steps are needed right now, remember this is a lifestyle change not a 3 month quick fix. The best and most stable/successful weightless is over a period of 1-2 years.
The best thing you have going for you right now, is just laying all your cards on the table and keep telling it how it is. Keep it real, keep it real for us, so people can support you. There are awesome moderators on here that want you to succeed.
Rock on, stay fab
