I've been reading lots of posts saying that people have been losing weight within only a few days of taking Xenical. I've been on them for 4 days now and have not lost a single pound. I have been eating very healthy low fat meals and not cheating at all apart from maybe one small chocolate cookie at night with my cup of tea (only because I was so good during the day). I have not had any side effects either apart from the feeling of needing the toilet but all is fine in that department.
I thought I was maybe expecing too much too soon but after reading lots of comments about other people losing weight almost immediately im losing hope
These tablets are expensive enough for them not to work. Anyone else in my shoes or has any info to tell me where im going wrong?

Much appreciated
