It really is trial and error that take s a bit of time working out to fit with you!!
My routine: -
Morning 2 glasses of water first thing.
Coffee (1st at about 7 am but I drink far too much of it through the day at the mo!)
About 9 I have a savory drink
Still sipping water
About 10.30 - 11 I have first soup. (Mushroom)
Another dedicated glass of water and coffee.
About 1.30 have half bar with another coffee.
About 3 have another savory drink and glass water
5- 6 pm sit down with OH and have soup (Thai or veg) I have this very watered so it takes time to imbibe so I spend more time at the table with OH. Water now soda.
7pm I either have the other half of the bar with coffee or the banana shake in frozen mousse form
8.30 I have the other of what I didn't have at 7pm.
Glass water
I have water with me all the time but I do have set times for actually drinking it too or I tend to lapse. (I hate water!) I have a small glass by the St Clements tub with 10 half wooden skewers in it, one end I've coloured black and the other red. I turn one over from red to black every time I have a glass and I know if I've had my quota then. 3 of my glasses = 1 litre. I also like the soda water in the evenings as a bit of variety! (I still hate water).
This is purely my way of coping. I find I'm so busy in the mornings I don't think about the packs and can get away with a late start. The savoury helps there. Not that I feel hungry anymore I can just get a bit shaky if I leave it too long! By evening things have calmed down and I still have things to look forward to and stop any boredom setting in. In the real world I'm not a boredom picky eater, but I can feel that way on this diet so I head it off at the pass.
Others will tell you their way I'm sure, it's quite interesting to see, but you have to fit it in and it will take a couple of weeks. And you have to find the pack you like.
Hope this helps.
