Joy,
You may be right about
not being able to take them together. I have one med that I can take with my Synthroid, but I cannot take my supplements at the same time as my Synthroid.
4 hours before eating sounds really long. I don't know what you have, but I've been on Nexium in the past & I only had to wait 1-1.5 hours until I could eat. Have you verified with your doctor that you have to wait 4 hours before eating anything?
If you have, I feel really bad for you. That must be so hard to wait half the day to eat or take your Synthroid. I would be so crabby.
feel better,
Frances
