Sorry I have not done a diet like this before, but just wanted to give you some encouragement on joining SW.
You seem to have lost an amazing amount on the lipotrim diet, so well done for that.
SW is so completely different to the diet you have ben doing that you might notice a small gain of maintain for the first week or two because your body will be going through a massive digestion change.
All I would really say is with this in mind give slimming word time to settle in - it really does work well, but it might take you a little longer to see this on the scales compared to someone who has not been on diet before starting.
Few things to help you make the transition;
Drink lots doesn't matter what but drink plenty - water, squash, diet coke, tea or coffee (milk from your healthy extra). SW recommend 6 / 8 glasses a day. Its important for cells to have enough water in them, but even more so when transitioning from one diet to another as adequate fluid really does help your digestion.
Eat plenty of fibre to aid the transition. You might see scan bran for sale in group, this is like fibre dynamite. You can have 5 pieces as a health B choice - they are not the greatest thing to try and consumer, but there is a section in the recipes to give you more palatable ways to consume. I wouldn't ever eat daily, but maybe once or twice a week (if you eat scan bran you must consume water). Again this is a digestion aid.
Enjoy eating food again, eat till you are satisfied (your appetite will probably be smaller because of the diet you have done) don't feel the need to eat lots, just eat till satisfied.
Don't weight between weeks, seeing a gain a few days in can be upsetting when by the end of the week it can be completely different.
Once again, don't judge yourself on he few couple of weeks, you might have great losses, but give yourself some slack to adjust from one to the other.
All the best.
