Ok so curious. It been hot here in the south east for past 2 wks and miserably so. I have not had fill in 2 mos and now lately my band I super tight and I'm nauseous during day. Yes I'm out working in this dreadful heat I'm not drinking any tea, lemonade or coffee cause doc says caffeine can dehydrate you etc. But I vomited 3x yesterday it was 100 degrees and this was after I drank half of mcdonalds wild berry smoothie. I've had these before with no problem. Within minutes of drinking felt like band was squeezing it and I didn't get relief til it came up. Prior to this I had been fine. I normally don't get nauseous, except when I eat too fast. Anyone else notice changes with hot weather?

My experience has been if I get dehydrated, the band get tighter. I'd just make sure you're drinking plenty of water throughout the day. Good luck!

Thanks that may be it because I've been very very thirsty and had some swelling other day. I think I will buy a small cooler and keep in my car
