Congrats on competing in your first meet! It sounds like it was quite successful.
Remember the meet is a long weekend! Especially if you had to do anything different nutritionally. It is completely normal for weights to feel a little heavier than they otherwise would following a peak like this. Additionally you need to build back up the volume a little since as part of a well designed taper you will have backed off on volume leading up to the event.
Don't worry you should be just fine by now.
