I want to lose a stone and my friend recommended these. I googled and found lots of good reviews. Anyway I was really sceptical but I bought some and I am on day 2 - yes they have suppressed my appetite majorly (and trust me I LOVE my food) also supposed to increase metabolisim - anyway I feel like I am on a low dose of amphetamines!! last night I couldn't sleep until 4.15am then kids woke me at 6.45 and I felt fine. I feel tired now but my head is buzzing like crazy!! According to my mate after 2 or 3 days I will be able to sleep better?!? I a eating but so much less than usual - anyone else tried these?
