Hi All, I started Exante on Friday so just coming to the end of my 3rd day . But last night and today I have had a banging headache, is this normal? Do you think it could be lack of caffine ?(I cant bear to drink black tea and don't like coffee!) When does it get easier? Please someone tell me soon! Drinking about 3ltrs water a day so am staying hydrated. But I know I need to loose the weight so I will have to carry on.
