Tips for egg retrieval

Hi ladies,
I have my ER tomorrow morning and am looking for tips to reduce the bloating and pain. Can anyone offer insight? I've been reading horror stories so I'm a little freaked out right now. Also, I'm confused about whether to drink regular Gatorade or G2 - some say to drink regular because you need the salt to reduce bloating, others say G2 because the sodium can lead to OHSS. Help! Lol.
