Metformin question

[HTU]

Just started Metformin 3 days ago. Taking 500mg before morning workout and 500mg with dinner.

My issue is it seems to make me very tired? Is this normal? Am I doing proper protocol? This is my first run with it, but have been using gear for 30 years. Right now using:
3 ius HGH day AM
1 iu IGF-1 day AM
700 mg Tren A / week
700 mg test prop / week
100mg A-50 day - 50mg AM / 50mg PM
LGD 30 mg daily AM

age 48 - 255 pounds

Never been this tired....thanks for any tips in advance.

You are supposed to take metformin with meals so maybe your morning dose since taken with no meals is causing your blood sugar to drop to much which makes you tired. I take 500mg only with a meal having 75g+ carbs otherwise my bsl gets low and I feel shitty.
