I can only speak as a pre sleever... but I'd rather get it over with.
We started looking at the sleeve idea back in February, and were waiting for finances to get moved around and a family wedding commitment before booked a date. I'd much rather have had it done there and then, instead of waiting.
I also think I will be less likely to want lots of food in the summer months (we're in Spain so it gets quite hot here). And I can make use of the cooler mornings and evenings to do some walking, and use our pool for swimming in once cleared for it after surgery. In the winter months I'll not be able to swim (as the pool will be too cold) and I love it.
I know some have found their liquids really hard, I'm finding it (pre op so far) ok.... and have been around people when they are eating. I can honestly say I have not drooled once....and found it quite a rewarding challenge to cope with it.
One way to cope might be to do the cooking,..... and busy yourself that way, rather than sit around waiting for cooked food that you can't eat. I get a lot of satisfaction from providing for people, knowing they can gain the weight not me!! LOL
Good luck
