I have been on sukkarto 500 for nearly 2 years 1 in the morning & 1 at night.i have for a long time suffered with tiredness & low motivation. the doctors have just recently increased my medication to 4 a day , I now feel totally wiped out all day , sleeping for 12 hours & still feelin shattered! the doctor says it’s not the sukkarto but mental moods , am I having mental issues or do other people suffer the same ? Cheers steve
