Can i take two 100mg doxycycline a day instead of 1 a day?

I am prescribed to take two 100mg pills of doxycyline daily. You can take 2 a day without any problems, however you are supposed to space them out. So take one in the morning and one at night. There are no reasons that you cannot take 2 pills a day. Make sure you take each one with a full glass of water, and do not lay down for at least 30 minutes. Also avoid taking any vitamins 4 hours before or after taking your pill. The only downside is that you will run out of pills twice as fast. Good Luck
