This is terrible and highly obnoxious, not to mention it makes you look like a complete amateur. Which you might be, but you want to look like you know what you're doing. Learn to memorize the suits! Here are some ways:
If you have a pocket pair and it's the heart and diamond, just say to yourself "I have red 99"
If you have AsKd, choose code words that are easy to remember. I use words that begin with the same letter as the suit. In this case, I go with "AK showdown".
If it was AhQc, I say "AQ holy cross".
If I have AhKd, I use "AK hi def".
For AhKs, it's "AK high school"
Try things like this. It's way better.
Also, nothing wrong with waiting until it's your turn to act to look at your cards. But don't take ten seconds. That's awful.
