What's 'HTP' & can it be bought over the counter?
it is
5-HTP (the 5 is important) and yes, it can be purchased over the counter.. can usually be found in the supplements aisle - being you are in the UK, not really sure what you have for stores, but I would expect that chain drug stores would have it. You should also be able to find it online... Natures Bounty, Now and Spring Valley are all reputable brands of supplements (at least here in the US), there are others as well, those are just off the top of my head.
This is a little bit of info from Mt Sinai...
What do 5-HTP supplements do?
5-HTP dietary supplements help raise serotonin levels in the brain. Since serotonin helps regulate mood and behavior, 5-HTP may have a positive effect on sleep, mood, anxiety, appetite, and pain sensation. 5-HTP is not found in the foods we eat, although tryptophan is found in foods.
I would suggest you research a bit more before spending money on anything - educate yourself on what it is, what it does, and any potential side effects to watch for. Dont just take my word for it, or anyone elses, for that matter. I would also suggest speaking with your GP about it and/or your pharmacist - to make sure there would be no interactions with any other meds you may be taking (shouldn't be, but best to make sure).
We all know getting a good nights sleep is crucial to how we feel.. it has helped me, but i also seem to have hit a plateau with it... or perhaps the neck issues are interfering more.. not really sure. I am still taking it every night, about 30 mins before bedtime, and I am still sleeping better than I had been before I started taking it.. but not quite as well as I was initially.. I may need to increase the dose from 50mg to 100mg... not sure yet.. Kind of want to wait and see how things go with the cortisone injection (Dec 8) before I make up my mind on that.
