Hello everyone! Who has used sleep consultant services?

Hello everyone! Who has used sleep consultant services? Did it help you get your sleep back on track or was it a waste of money? I'm going to wake up every 1.5 hours at night soon... I used to sleep well, I was rested, everyone was happy... I slept for 5-6 hours then every 3 hours I would wake up... in normal circumstances, one should sleep for 10 hours, but he sleeps no more than 7... He became capricious, can't stand his waking time... there was a case when he fell asleep only after 12 o'clock, and he missed 4 hours without awakenings... but it's not possible to keep doing that...
