My psychiatrist put me back on half of a 2.5mg dose of Olanzapine daily, and along with it has advised me to take 500mg of Metformin three times daily. I was only taking the Metformin twice daily, but because I have gained a few pounds, my doctor thought it I should take more. I'm not sure if it's just a coincidence that since taking three I have had a persistent headache, have been generally sick to my stomach, and just not feeling well. I know it's also flu season, so I'm not sure if maybe I have a mild form of the flu and it just so happens that I upped my Metformin dose at the same time. Since not feeling well, I have dropped a couple pounds: my appetite has gone from being increased to drastically decreased (it doesn't help that any time I eat my stomach feels worse). I also think these pounds are fairly superficial since I have also been on my period and my weight tends to spike at the beginning then fall once it's over. I'm not sure if I'm really making any sense.. my concentration is really low and so is my energy.
