I am a firm believer in low carb so I usually don't eat a lot of bread. I have just found that by not consuming bread, rice potatoe etc I feel better and lose weight but in saying that every body is different!
You could do an open sandwhich? One slice of bread and toast it? I find myself having lettuce cup "sandwiches" with salad fillings and chicken or ham. It doesn't look like much but I am always so full and satisfied afterwards from the lettuce!
A couple of raw almonds will keep hunger at bay at that 3pm slump until you have dinner.
I am ending my 2nd week on 30mg and have found the extra energy has worn off a bit too so I feel it is normal.
We all know it is hard to change our habbits but the longer we stick to them the easier it will become, and the more weight we lose!
You must be doing well to lose that much already so please don't give up.
We are all human and will go off track every now and then but so long as you start back on your healthy eating and exercise straight away that is all you can do (took me a while to realise that one..)
Feel more than free to message me on here, I'm always lurking around with plenty of time until study commences again!
