Last night I was really shivery in bed. Woke this morning and didn't feel too bed so went swimming. Around lunchtime I started to feel light headed and had to lie down. I started feeling shivery again and my whole body has been aching most of the day. I had a few stomach pains a little earlier but they have eased now. Has anyone else experienced anything similar whilst on xenical. I don't seem to have a cold but have been coughing a little. I just wondered if it might have been a side effect. I did have some wine last night too.
