Here is another great article by Mary Shoman.

There is one thing that confuses me though, she says thyroid patients can use Aspirin, I remember reading somewhere once that we shouldn't take it at all. I can't remember where I saw it though.

When you say "we", do you mean thyroid patients or people in general?
I know that Aspirin must not be given to children. But there are loads of older adults who are on Aspirin for blood thinning reasons.
The problem for children is the risk of something called Reye's Syndrome.

I'm sorry, I mean us as thyroid patients. Not people in general.
Well, actually, Mary said that herself about 15 years ago! She must have had a change of heart. I remember clearly, because it was not long after I was diagnosed, and avidly reading all she had to say. And she said no more aspirin or Alka-Seltza, and I was heart-broken, because I practically lived on Alka-Seltza at the time. But, I've been very good, and not had a drop since then! However, if she's changing her mind, I'm off tomorrow to buy a box! lol
You could well turn into a white goose then. 
Perhaps this abstract contributes to the discussion:

Hemostatic defects in response to aspirin challenge in hypothyroidism.
Zeigler ZR, Hasiba U, Lewis JH, Vagnucci AH, West VA, Bezek EA.
Abstract
A patient with hypothyroidism had ingested aspirin and bled profusely following dental extraction. The only abnormalities noted on coagulation survey were a prolonged aspirin bleeding time and reduced retention of platelets on glass beads. Based on this index case, an additional 12 hypothyroid patients, on no medications, were evaluated for a mild bleeding disorder, including studies with aspirin challenge. The results indicate that thrombin-induced platelet serotonin release, following aspirin ingestion, was subnormal in most hypothyroid patients. However, only hypothyroid individuals with TSH levels of greater than 60 microU/ml have an increased hemostatic sensitivity to aspirin, as measured by the bleeding time test. These findings did not appear to result from decreased synthesis of the factor VIII-von Willebrand factor complex. As this drug is commonly ingested, the effects of aspirin on bleeding may explain the easy bruising and menorrhagia that occur in hypothyroid individuals.

Don't miss that acquired von Willebrand's disease is another issue that can occur in hypothyroidism.
and "acquired von Willebrand's disease"

bit confused about what the bleeding time was,
and B12 for bruising

PS I used to take Sudafed but it just seemed to make the cold last longer, then a chap at work went to hospital with a Sudafed overdose and unable to walk - put me off a bit really.
"12 hypothyroid patients on no medications" , no levo etc?
