I have been on Xen for a month now, last week I had a sickness bug so didn't take it for 2/3 days....I restarted on Friday and I'm poorly again! I don't know whether I'm not over the bug and the Xen isn't helping? I'm hardly eating as I just don't fancy anything and I feel absolutely drained!!!! Just wondered if anyone else has experienced any type of illness related side effects?? I don't want to give them up!!!!
