Diabetes I type case, in details, sugar levels

After session 12 on Oct 28:

Oct 29 - 11.2

Oct 30 - 10.2 in the morning then dropped to 4.0 and the whole day he was experiencing  hypoglycemia;

was eating constantly but sugar level was not rising.
Oct 31 - 15.0 probably as a result of yesterday's efforts to raise sugar level.

He's having 10 units of long-acting insulin twice a day and 8-10 of fast-acting.
