I got back from my europe vacation 5 days ago and I only had once diarrhia on this trip. Otherwise I was fine, just tired from the trip and heat. I posted before that I have problems with no appetite but on this vacation my normal appetite came back. Strange ! Now I am back and it's like the old days, no appetite. How can that be ? Also, on this trip I lost 3.5 pounds ( 16 days). I did pay attention what I ate and I was the only one avoiding dessert since I didn't want to gain weight. We did walk a lot during the days when we went shopping and sight seeing. I am just wondering why I lost 3.5 pounds. I thought I just ate normal to keep the weight stable. Is this weight loss worry some ? I am actually glad about it but still worried. I am now about 135/136 pounds at height 5'8". Looks good, but it's strange. What's your input ?
