Glucose readings

A bit all over the place lately, mostly high, due to the anti-inflammatories im on for the Costochondritis (which by the way doesnt seem to be going a way, physio here i come) with huge low dips occuring more often than id like. Today i hit a low of 1.7 mmol/L (not my record low which was when the meter read LO- meaning below 1.1), which was really scary as i almost lost conciousness, still not the better of that one. 
Hopefully tomorrow will be the start of me controlling these sugars, Wish me luck :) xxxxx
