Hobler,
My oldest daughter concoted an Herbal Bug Repellent last year and it really worked well. I will see if she can remember all of the ingredients and post them here, so you all can try it out. Like most of you, she and myself do not like using the chemical bug repellents as some can be very dangerous if you inhale the mist, absorb them into your' skin, get them in your eyes, etc., etc. ... There are a lot of Herbs that will repel most bugs and ticks and when some are mixed together the right way, they will keep most anything away and probably even attack dogs! Yeah, some smell bad while many others do not, so you have to mix more of the good smelling ones in to offset the bad smelling ones.
I hope that your' heart has gone back to normal rythm without any complications! For your' knee, the Vitamin B-6 Complex will help with that as well as try some natural remedies and pain relievers. You should be able to find most of what you might need in the fields and woods near you. (See the link below for some natural solutions.) Just make sure that you mix them correctly and take what is recommended, as some herbs can be harmful in large doses or used over an extended period of time.
