I recently started taking MSM (about 3 days ago) first day I took 1000 mg tablet on my way home from work (I stopped at a local supermarket at 5:15 am cause I work overnights) and had insomnia that night... should have read not to take it before bed. So I tried it the next day 1000 mg 2x's. Felt exhausted, slight headache and I drank distilled water about half a gallon.

Next day I took 3 tablets (1000 mg each) finished the other half a gallon of distilled water and had same symptoms. I woke up after that my eyes were pounding in my skull worse headache and exhausted more than usual. I want to take advantage of the benefits but I can't do 2 weeks of the detoxing.

Could it be I got a low quality (wegmans brand MSM), taking too high a dose (i weigh 230 6'5 male) , or is it just not for me? I take atenolol for pre hypertension celexa for my social anxiety, and aderal for adhd. my anxiety gives me slight ocd like behaviors as far as "ticks" go. I have zero emotion on the meds so I'm trying to get off them.

I was so happy to find this site. I took 2 tsp MSM for 2 days and 1/2 tsp for 2 days and 3 weeks later I'm still having reactions. I wake in the middle of the night with my body buzzing and I'm having headaches (which I've never had in my life). My energy level is very low. I'm 75 and very healthy otherwise; I'm still working as a substiture teacher. I'm allergic to sulfa and that may be the problem since some others on the site said they were unable to take MSM because of that. I was really hoping it would help with my shoulder problems. I have a damaged rotator cuff (inoperable) from hairstyling for 34 years.
