James - I had to train a client around this time so I didn't have access to the blender I would normally use. Instead I put the dry ingredients into a zip cocktail lock bag and the other ingredients into the shaker and a plastic container. Because I didn't have the blender I actually ate most of this 'shake' and drank the rest of it. Energy levels are just like normal, it's just the abundance of time that seems to be an issue!
If your dad 3d motion multi directional instead get a kick out of cool things think of giving him a temperature-controlled wine cooler instead of the more obvious barman cocktail shaker set. Or, you might like to give him a groovy lamp shade made of recycled materials.
The main reason is this, most conventional drinks and shots are a quick fix, a temporary solution to a permanent problem. So by going the herbal route, you're helping your body align itself, and you're creating and restoring balance within. Many of the problems that we have stem from ailments, some are minute and others very serious. So by utilizing herbs we treat the condition on a different level. I'm not saying teas and things of that nature are a permanent resolution. But what I am saying is that you may find a long term relief solution to your problems.
Reduce the heat inside your home. Keeping the temperature too warm causes the air to dry out, which is as bad for your breathing as it is for your skin. Plus, you're more likely to be lethargic in a room that's too warm. If you're slightly chilled reach for a sweater instead drinks rotational of the thermostat.
Jitter-Ring / Gyro Ring - The Jitter ring is really just 5 little tops of slightly unusual design which are strung onto a metal ring so that they can freely spin. The discs can spin up to 1000 rpm! Makes a very pleasing rattling spinning noise.
And lastly, while it is not necessarily a drink, the 5 hour energy shots will give you the same results. These are not going to have you "crashing" like a lot of energy boosters do and it is said that they are all natural. When you need something that is light, give these a try.
