I have it I hate it.
2 years ago went to the doctor and he put me on some little orange tablets. Best things ever. Take one hour and a half before bed. Puts you to sleep. Used to last from like 10 mins after taking it till like an hour or so before. Were amazing. Stopped making them for some reason.
Now on Benadryl one a day things that to be honest are whack. Usually one of those and a few piriton a day for me.
Have runny noses, sore eyes, and heat rash. Sucks.
