Get a new piece of exercise equipment yfor home you can afford and feel positive and excited about. Diet, eat plenty of fruit and veg esp. green stuff - good for your skin and try to exercise for 30-45 a night. Put some music or depending on what you are doing tv and exercise away.
Oh and as said feel positive do not get on the scales to much try and chill because the stress cannot help. Try to focus on health rather than losing weight all the time, I know its difficult but it does help.
No not drink booze, eat junk food, or snack.
