100% yes but not all the time- it comes and goes but it is dreadful. I believe it is because hormone levels are at their lowest in the early morning which is why we often wake up sweating at 5am.
At my worst I would wake up drenched in sweat and have to rush to the toilet in a panic- I had this on holiday last year every morning in The Maldives, and it made breakfast very difficult as it kept coming in waves, and I would have to leave the dining room to find a toilet. It was worse there as of course it is very humid. Especially bad was the morning we flew home as we had an early start, and I was having attacks even on the plane which was horrible as of course it affects the bowels- then you panic more in case you are not going to get to the toilet in time.Of course you do but in a confined space you think otherwise.
It does get better, I am not as bad at the moment and do not wake up in this state very often- however my periods came back in the summer and so I think I have more hormones at the moment, or at least they are not fluctuating as much.
