I\'m on my 3rd day of taking this... and I\'m hoping things get better! I haven\'t had the jitters but the nausea it terrible! I took 2 for breakfast and 2 for lunch the first day and I actually had to leave work early I felt so sick. Yesterday I only took one at lunch and I didn\'t feel so bad. Today I took one this morning and one at lunch and again, I\'m thinking about leaving early! On top of all that, I\'m living in the bathroom!! Anything I eat seems to \"run\" right through me. My advice for any one looking into this product: start slow. Start with one pill a day. If that doesn\'t bother you, take it up to 2, etc. Also, buy stock in toiletpaper; you\'ll poo your brains out! =) Good luck!
