Raising of blood glucose levels is not listed as one of the side-effects of Estazolam, my friend.
This is what the following webpage states are the side-effects:
"Stop using estazolam and call your doctor at once if you have any of these serious side effects:
> weak or shallow breathing;
> fast or pounding heartbeats;
> confusion, slurred speech, unusual thoughts or behavior;
> hallucinations, agitation, aggression;
> thoughts of suicide or hurting yourself;
> restless muscle movements in your eyes, tongue, jaw, or neck;
> pale skin, easy bruising or bleeding, unusual weakness;
> fever, chills, body aches, flu symptoms;
> problems with urination; or
> nausea, stomach pain, low fever, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes).
Less serious side effects may include:
> daytime drowsiness (or during hours when you are not normally sleeping);
> amnesia or forgetfulness;
> muscle weakness, lack of balance or coordination;
> numbness, burning, pain, or tingly feeling;
> headache, blurred vision, depressed mood;
> feeling nervous, excited, or irritable;
> nausea, vomiting, stomach discomfort; or
> dry mouth, increased thirst."
I'm not sure where you think the side-effects are almost the same. They are NOT.
