Please, please, please stop taking that much of the medication. Don't let someone else cause you to take those pills anymore. Only take them if YOU think you need them for what they are prescribed for.
If you have a headache, just take the recommended dose. If it doesn't work, try something else after that's out of your system. You certainly don't need to add a physical health condition on top of anything that you're going through right now.
Please take good care of yourself,
Missi
