Try weaning yourself off the ephedrine very slowly, should make it easier. Just decrease dosage by 10% each week and you should be able to get yourself off (10 weeks total to stop).
Ephedrine was banned here in the USA in 1994. People were dying of heart attacks.
I am really a huge fan of yours Scooby but I wanted to call you out a few mistakes that are surely due to misinformation because it seems that you have posted a similar sounding reply in another thread.
Ephedrine per se isn't illegal neither in the USA nor UK. If one were to look at the laws one would see that only ephedra was forbidden to be sold as supplement or additive in fat loss products. Ephedra is illegal ephedrine or it's better known pharmaceutical extract ephedrine hcl are still perfectly legal and are used for example in the so known Coast Guard Cocktail and can be bought over the counter in any pharmacy for that purpose as well as in order to cure asthma (ex Bronkaid) and many other uses. Also as a pure herb or tea, má huáng, containing ephedrine, is still sold legally in the USA.
Also it was officially banned from use in supplements and fat loss products only in 2004.
The ban was enacted more due to media pressure and to combat what people call meth (methamphetamine). Ephedrine and pseudoephedrine can be used to synthesise this drug in home conditions. A few deaths were exactly what was needed at that time.
Also most of the side effects were completely exaggerated by pseudo-analysis. Deaths were mostly due to overconsumption of said chemical which is not unexpected if people go by the stupid logic of more is better and for having completely ignored suggested dosage. And seriously if I were to look I would say that there are more deaths by water intoxication or by a huge margin by alcohol or cigarettes then by ephedrine.
If anyone is selling supplements with ephedrine in it I can assure you that it contains no active alkaloids so they are basically selling an ineffective and useless form of that drug. Bottom line don't buy it.
That said I agree with what Scooby's suggested. It seems indeed that you should gradually decrease. I believe you addiction is not only of chemical but also of psychological nature. Also using it just for increased intensity is really not intelligent. Even people using creatine do cycle it.
If you have any questions feel free to ask.
